How to Build a Road

[@274pacific]

The amount of research needed to summarize the thought process of forgotten civil engineers from decades ago is truly impressive.

[@DarkHarlequin]

I think it's really really easy, with all the issues we're facing as mankind and states, to forget what marvels of enginiering, sociology and planning our modern society is. Highways, skylanes, modern building, electrical or water infrastructure are all incredebly mundane things for us that are incredible feats of planning & design if you look closer that would be called miracles by people just one or two-hundred years ago. We can't be constantly in awe, and we should strive to adress the issues of our time but sometimes it's good to remember what amazing feats our modern society is too.

[@garolopez887]

I think some of the modern tunneling techniques today would not disrupt wildlife in that spot.

[@loldoctor]

Yes, we should thank the people at Mead & Hunt who already did that research and published a 76-page history on the topic in 2019, entitled "Vail Pass Segment of Interstate Highway 70" and freely available online. As far as I can tell, this document serves as the source for almost all of the historical narrative presented in this video, as well as many of the figures. It's in their works cited in the description. I like Wendover Productions a lot, but their talent mostly comes from how they present information in a digestible manner with helpful visuals, a well as their choice of esoteric but fascinating topics. And of course it would be impossible to do extensive and original research for their videos given the rate at which they publish them. I think their research skills come more from taking aspects of a narrative and elaborating on the logistics, for example using a Florida study to understand the issues in Colorado. Obviously this isn't hard to find, government studies are extremely easy to find and they cover every aspect of infrastructure.

I was a hazmat driver who had to go over a lot of those passes every night, no matter what the weather was. Some of the scariest shit in the world. The only time we were allowed through Eisenhower tunnel was when Loveland pass was just impassable and we would have to wait, CDOT would close the tunnel both directions and escort all hazmat trucks through without any cars in the tunnel. Pretty crazy.

Yea, they still do that. They have a traffic light up there now. I have to wait on your guys every winter when the pass is closed. Love this rocky mountain ice skating!

[@MileHighGrowler]

@@mikerheynolds2193 And the worst part of those closures is when it's actively snowing because the lack of consistent traffic allows the road on either side of the tunnel to ice over more easily, making it one hell of an ice rink for the cars once they re-open it.

As a Highway engineer practicing in mountainous areas of the East Africa Rift Valley, I appreciate the accurate research you have done to show the amount of work that goes into designing & constructing a highway project in a challenging topography. It's amazing to see how the design standards have evolved through the years. Even though we use also use AASHTO to supplement our design, we are forced to use 8% superelevation because we couldn't be certain that the traffic would actually adhere to the design speed due to the cultural speeding in East Africa.

[@vigilantcosmicpenguin8721]

I never considered that cultural speeding would be a factor that engineers have to consider. In America, we take a lot for granted about our road system.

The crazy part is, I-70 is considered a safer route in winter than I-80 up in Wyoming. I-80 in Wyoming had less engineering challenges, but is legendary for horrifically bad weather in winter and the section between Laramie and Rock Springs is the windiest region in the entire US excluding some high mountain summits. Hurricane force winds are a very regular occurrence in southern Wyoming. Combine that with heavy snowfall, ice, and regular below zero temps in the winter and its a frozen hell on earth.

[@hgman3920]

The story of I-70 through Utah is another engineering marvel in an of itself, not because of the terrain, but because of how absolutely remote it is. For example, there is a stretch of interstate almost 100 miles long with absolutely no services (food and gas). The route follows an old railroad corridor which the Union Pacific railroad surveyed, but never used because of how remote it was. When the first highway surveyors showed up in the area to plan the route of the new interstate, the local ranchers thought they were absolutely nuts to build a road through the area.

[@middlemuse]

Declined a second date with a girl I was very attracted to because she told me that she once was driving west while high and took that stretch without getting gas first. She had her dog in the car and there are SO MANY signs, I just couldn’t handle how dangerously irresponsible that is.

My grandfather drove the 1940s highways through this entire region from Denver and Pueblo to Salt Lake. He remembers driving home in a blizzard, getting out, walking 20 feet or so to see where the road went, getting back in, driving that stretch, repeating the process for hours until he got to a town. That story he told freely. Other stories I had to press him to tell as much as he would and I still get chills. America's highways are soaked in red, there's just no way to avoid the fact. I'm still very proud to be a 5th generation native of Colorado and I hope I get to stay forever. Thank you @Wendoverproductions for such a deep dive into the Rockies roads.

Would Red Buffalo Pass be worse in winter or better? We lived in GJ for 7 years and would travel over to Denver every Thanksgiving and, like clockwork, the road conditions were always icy.

As a child, my family lived in Colorado but my grandparents lived in Utah. To visit them we either had to drive up through Wyoming on I-80 or take the I-70 route. Going through Colorado was our favorite as it was way more beautiful and fascinating even if it was a few hours longer, but after a couple of Christmas trips through terrible conditions we decided to only take I-70 in the summer. In fairness, I-80 in Wyoming has harsh winters too, with permanent checkpoints to shut it down for excessive blowing snow, but it was faster and flatter with less canyons and turns. My father would have to take enough time off from work to give us the flexibility to wait out the weather if a winter storm blocked our return trip home. It was worth it, these highways made all of my memories with my grandparents possible, and are a part of what I call home

[@mattcolver1]

The highway through Vail Pass is impressive, but really the most expensive and difficult section to build was through Glenwood Canyon. That section of road is essentially all bridges and tunnels.

[@mikerheynolds2193]

and rolled over super truckers at the eastbound entrance. Seen the scars in that curve lately? Last winter it seemed like every week there was one rolled over between there and No Name. Boy, I can't wait to see what this winters holds!

[@mycroft16]

Yeah, the constraint on construction through there was "don't touch anything." They had to keep track of the plants that would be impacted and move them as little possible. And it's a stunning drive, the way the freeway rises and falls and soars around and through the canyon.

[@middlemuse]

My mom had to pass through Glenwood Canyon while that stretch was under construction WHILE SHE WAS IN LABOR. I wasn’t there but it sounds like it was a pretty traumatic day.

[@mycroft16]

@middlemuse I remember going through the construction as a kid. It was one way so they'd halt a whole side of the freeway for 45 minutes while the other direction came through then switch. I remember crossing the freeway and going down to the Colorado River and playing for half an hour when we would drive from Denver to Salt Lake.

The Grizzly creek fire and subsequent mudslides have made the canyon a shitshow in the past few years too.

I'm actually a civil engineer in Colorado doing roadway design! My company is actually working on the reconstruction of the west side of vail pass! I worked on that project a little and I got very familiar with it. Colorado's mountain roads are about as a crazy as it gets in the US. If you want to see a real piece of engineer absurdity look up the Million Dollar Highway, US 550 between Ouray & Silverton, a road not for the faint of heart!

[@chinguunerdenebadrakh7022]

Not completely related, but US infrastructure spending is often judged to be much less efficient. In subway construction, for example, US was paying like 2-3 times more per km than peer countries like France. The US paid about 550 mil USD/km on average for rapid rail transit. It was 310 in Australia, 300 in Germany, 250 in France, 260 in Canada, 200 in Austria, 190 in Norway, 130 in Switzerland. (UK and NZ were few that had higher prices than the US). This has nothing to do with labor costs as if you look it up, Norway and Switzlerland have very high GDP per capita figures (only IR and LX are higher) and they build at one of the cheapest prices. One of the things they point to as the cause is that US just doesn't build consistently. There'll be a big burst of spending for maybe 5 years and then it spends, the institutional and technical knowledge gets lost and when it starts falling apart 30 years later, it's basically starting from scratch. Successful cities/countries, on the other hand, keep building, always.

[@YAOMTC]

@@chinguunerdenebadrakh7022 wouldn't economies of scale also come into play here, since the US has much less in miles of passenger rail per land area than those countries?

[@gobbel2000]

The crossing of the Alps was similarly a very big challenge for a long time, because there too is a tall and steep mountain range stretched across the Alps without any larger valleys cutting through it. Since 1967 there is the Felbertauernstraße with a 5.3km long tunnel which was large enough for trucks to pass through. Later in 1971 there was the highway over the Brenner, which is still by far the most important road connection between Austria and Italy. That highway is bridged up for the most part. I can't compare it directly to the I70, but it must have been quite expensive to build. High demand is now causing frequent congestion there, mostly from trucks. That's why a 64km long rail tunnel (Brenner base tunnel) is now being built that simply cuts below the mountains and should take over most of the cargo traffic. In Switzerland the Gotthard base, opened in 2016, has a similar concept with 57km length. From what the video told me I would say that I70 is situated much higher around 3400m, whereas the Brenner highway is only as high as 1400m. But the Rocky Mountains around there don't look as steep as the Alps.

[@dejfcold]

​@@YAOMTCyes but also no, I guess. But we can't predict the future. Would it even out if the US built always, so that trains would be more accessible, so more people would travel, so more money is collected from fares, so it could be cheaper, so even more people would travel, so there would be greater demand for better rail, so etc etc?

As a lawyer especialized in public procurement, our firm does a lot of legal consulting for big infraestructure construction companies, but all the minutia of the engineering of the roads our clients do flies over my head😅 so this actually explains a lot! I live in Chile were most highways have to pass through some sort of mountain, similarly to this one.

THe drive on this road is absolutely breathtaking. The only thing that distracts from the ethereal beauty is pondering about how in the heck the road could have been built in the first place. I know it was explained in the video, but the way in which the road hugs the natural curves of the mountains and seamlessly flows above the rivers and through the tunnels makes for a one-of-a-kind drive for both the driver and passengers.

All the fencing and the ramps on either side were covered in vining plants, so the wildlife see it as a safe path. Seems like it works too bc there was very little roadkill when I drove through that stretch. Was very cool to see that attention given to the local animals!

As someone who lives in the mountains of Colorado, Eisenhower Tunnel is infamous if you’re going to or from Denver. If even one person spins out, it can lock down the road one way or another for hours. Vail pass is even more infamous. If you’re going to have sketchy weather, if you’re going to have whiteout conditions, it’s gonna be vail pass. Whenever we go from glenwood to Denver, we don’t say we’re on the way until we’ve made it past both. IF you can get through Vail Pass, IF the traffic through Eisenhower isn’t terrible, then you’re on your way. My personal record for waiting on Eisenhower Tunnel is (not joking) 5 hours.

Being a road makes this video even better

[@coleperna4345]

Indeed!!! I feel like I’ve been looked after ❤

[@garycrawford4700]

As a 6th generation native of Colorado , I remember road trips across the state on Hiway 6 and Hiway 40 . That's all there was when I was young. One of my Great Grandfathers founded Grang Junction and Delta ,so we crossed the state many times ,to visit family when I was young . Loved fishing on Grand Mesa . Anyway ,I grew up , became a heavy equipment operator and worked on building I 70 through Stratton , Rifle & Ten Mile Canyon. 44 below zero in Ten Mile , Thanksgiving weekend, 1978 . But all the peat bogs were frozen , so we could work . Good times . Thanks for draglining up good memories

[@MakerOnTheMove]

As someone who has traversed a good amount of the interstate highway system, I have said for years that I-70 west of Denver is my absolute favorite to drive because of how stunningly gorgeous the area is.

[@Sailor376also]

Wendover, you missed the near and next large problem for I-70, the cut through the San Rafael Swell , just west of Green River, Utah. The Swell is a roll of rock that resisted men on foot, horseback, railroads , and roads for centuries and millennia. Where I-70 passes through and over the Swell it began as a cleft in the cliff face, Spotted Wolf Canyon, that was 6 feet wide. Surveyors could reach out and touch both faces with their hands as they walked, worked. 8 miles of I-70 in total took 20 years to build, and drilled and blasted 3.5 million cubic yards of rock. The deepest cut is more than 400 feet deep. To road engineers this 8 miles is perhaps The engineering achievement of the Interstate System.

[@ShadowRaptor8]

I'M SO EXCITED FOR THIS! As a Coloradan it's so frustrating when people complain about the mirscle that is I-70 because they're running late for their ski run. I've driven that stretch dozens of times in my life and everytime leaves me in awe.

[@n0pe213]

I think you would love learning about US 550 or the million dollar highway between Montrose Colorado and Durango Colorado. Some incredible engineering and history. I think you would also enjoy doing a deep dive into avalanche science and how it impacts transportation and safety. You talked about it a little bit, but many folks just don’t want to realize how much work goes in to keeping mountain roadways open.

[@jacobdoddington123]

0:20 I don’t know if anyone else noticed, but the slope counteracts *_centrifugal_* forces, not _centripetal._ Centripetal forces are actually what keeps matter close to the axis of rotation, counteracting centrifugal forces, which pull matter away (i.e. if you swing a bucket of water, the _centrifugal_ forces keep the water in. This means the slope of the road actually creates _centripetal_ forces itself.

[@TylerMcHenry]

I'm betting the writer "corrected" some of the information that they researched after remembering being told that centrifugal forces don't really exist, but without understanding that they aren't just interchangeable terms. And centrifugal forces don't exist as a physical thing -- the car isn't being pushed out of the loop by some magic force, it's just going to keep moving in a straight line until something makes it curve. But you can still talk about them meaningfully in a mathematical sense (e.g. from the car's inertial reference frame), and it would have been reasonable to say counteracting centrifugal forces here. But even more correct would be to say that the ramps *increase* centripetal force. So the statement is exactly backwards from what would be true.

[@bearcubdaycare]

​@@TylerMcHenryWhat forces "exist" depends on your reference frame. In a rotating reference frame, centrifugal force definitely exists.

[@tonylee1667]

@@TylerMcHenryit's all a model, nothing really exists, only practical and useful mathematical representations of physical observations

[@frafraplanner9277]

Actually 🤓the slope helps to add centripetal forces so that the inertia of the automobile doesn't take it off the road

[@djmiller7192]

​@@TylerMcHenry If we're nitpicking, wouldn't the total centripetal force in the plane of the turn be the same? Just turning some shear force on the tires into normal force

[@mycroft16]

Grew up in Denver. I remember when they build the Glendwood Canyon stretch of I-70. Took years. It is one of the most impressive and beautiful stretches of interstate. And Vail Pass is remarkable. Another fairly crazy bit is the drop from Evergreen down into Denver. It's steep with some fairly hefty turns. The whole drive over the Rockies is beautiful and impressive.

[@Nickalzz]

Been on this a bunch of times and there’s plenty of spots that are extremely sketchy but it’s so beautiful and seems like the mountains go on forever. There’s so many it goes on for hours. My friend is a truck driver and he said they don’t even let him take 70 past Denver because of how crazy it gets.

[@Richardsmithabcd]

I ran that route for three winters. Every new image in this video was completely familiar except the under construction parts. Vail pass has a 7% section. If your EB and fully chained, you will spin to a complete stop with fresh snowfall. It's steep. Loveland Pass is not for the week of heart. Very few guardrails and steep on the east side. Glenwood Canyon is spectacular. The fire he spoke of was a transportation nightmare. I now get to sit in my living room when it snows. Nothing better. Carry on soldiers.

[@JAF30]

I remember going through that tunnel way way way back in the early 90s with family, we took I70 to nearly the western end and then came back the scenic way.. hitting a number of parks and sight seeing stops.

[@Sailor376also]

Immediately west of Vail pass one of my first jobs was installation of cut and fill culverts. Culverts between 6 and 11 feet in diameter, crossing both east and west road beds. The cuts excavated by surveyor scope and large excavators,, I was the guy to enter the ditch and with a shovel and by eye, flatten the center of the ditch to receive the culverts. I was one of the men assembling the sections and on the fill teams compacting the spoils to 95% and greater to bury the pipe. 1971-1972.

[@j.mieses8139]

Well done. The fact that highway was built was a marvel of engineering!

[@free-1-speech-1]

Thank Edgardo Contini, master engineer, for the Glenwood Canyon masterpiece of road design and construction. Contini was a visionary with the charisma and character to bring around anyone not understanding how design can truly transform the landscape and nature. He was an educator and consumate professional. His love and intuitive understanding of nature deeply inspired his students and colleagues. And, he had a wicked sense of humor. His fingerprints are everywhere, inspiring us 30 years after his passing.

[@fordson51]

This feels like a continuation of the Interstates video you did a little while ago. I have gone over this chunk of I-70 between Denver and Grand Junction in every season. Climbing the mountains in late evening with the sun low behind the distant summits is incredible. Take the trip if you have never seen it. Absolutely breathtaking.

[@neils5539]

The westbound stretch through Glenwood Canyon is the most beautiful section of interstate in the US. Just spectacular!

[@Saltiren]

This is awesome. I recently drove over the cascades and was awed at what man has done to be able to safely move so many people back and forth. This explains a lot of that process. Thanks Wendover guy.

[@taylorverrall118]

I love how when you talk about “The American Federal Highway Administration” at 0:34, the visual is of the start point of the Canadian Sea to Sky Highway near Vancouver 😅

[@McNasty_0]

man I left work to relax and watch some Wendover, did not expect to hear Sam explain my job while eating dinner today thanks for the amazing video as always, this stretch of I-70 truly is an engineering feat and one of the most beautiful drives in the country.

[@Aholeintheozone]

I didn't know a lot of this and I have lived in Breckenridge for 8 years. There is also a bike path over vail pass and it's a great climb.

[@spinachbb]

Can't begin to fathom a tunnel under Red Buffalo Pass, the eagle's nest wilderness is just incredible and I'm glad 70 was constructed so late in the game to where we'd finally realized that it's not always about "taking the fastest route."

[@danielb2571]

One of my favorite drives was traveling on I 70 between Utah and Kansas. 15 years later, I clearly remember passing through Eisenhower Tunnel. Thank you CDOT.

[@nick.v.g]

Fun fact here in the netherlands we have build aquaduct's where the canal with water it self is going on top. It is very strange to see a boat using a bridge. It cost about 200mil. We also make viaducts for animals to go over the roads to connect multiple small nature peaces to gether

[@michaelbeahn5977]

What an amazing video. Well done! I’m a native Floridian who loves Colorado and taking I70 out into the mountains. At a temperate time of year. However, I have driven out to Vail in the winter and with a decent snowstorm coming in close. Almost had to find a hotel room in Vail as they closed the interstate for a little while. The Vail pass is utterly amazing to drive through in winter. And while this Floridian was sure anxious to drive it, I never felt full panic as the road was smooth and clear the whole way.

[@theamazingcheese001]

Building a tunnel under the continental divide sounds interesting when just talking about it, but the weirdness is truly driven home when actually being there. I can't count how many times I've entered Eisenhower tunnel in sunny and dry conditions, only to come out the other side in a full-blown blizzard.

[@chrism3784]

I'm from the southeast, I've driven through I-70 twice from east to west, what an amazing landscape it is. I love how it starts with alpine mountains and after vail slowly turns into high desert.

[@Hogslice]

You never cease to amaze me with the amount of information you provide in each video. It blows my mind. This is tantamount to a semester of college in road building 101. I marvel as I drive across this country at how many miles of great freeways we have and how easy they are to navigate. I've driven from the Pacific to the Atlantic and Canada to Mexico and we are so blessed to have great freeways to make the travel so enjoyable. Thanks again for the video.

[@ThePackDad]

I live a mile from the eastern most last 30 miles of 70. We take the kids on a lot of road trips and I'm always amazed and talking about its construction. I really keep them entertained with the same facts i told them the last time. 🤣I do enjoy 70 and it's far more incredible further west.

[@farikkun1841]

im from developing country, after watching this video, there's literally another video of roads from my area, the contractors just put 50x50 concrete on the ground with gaps between them and call it a day. And very popular channel here is compilation of overloaded trucks slipping their tires trying to climb non-standardized mountain pass roads. No matter what people on internet say about US, they have better goverment than mine

[@SephTunes]

Just drove this road last month last time on the way to Oregon from NC. The most beautiful thing ive ever seen in nature.

[@jsmith1845]

Would love to see a similar video specifically about the history and challenges regarding I-70 through Glenwood canyon in Colorado. I imagine that was an even tougher section to plan and build.

[@EarlBulwer]

When you begin to touch your heart or let your heart be touched, you begin to discover that it's bottomless.

[@starrwulfe]

I drove this stretch of highway for the first time a few weeks ago; nice to see the back story of its construction 😊

[@MichellWoolf]

He realized there had been several deaths on this road, but his concern rose when he saw the exact number.

[@michaelengelhardt5336]

Drove the whole route from the Utah border to Denver earlier this year. Beautiful stretch of highway. A true engineering marvel. Besides the areas mentioned, the highway around Georgetown and Idaho Springs is really cool because the valley gets so narrow the two directions are almost on top of each other.

[@johnchedsey1306]

Colorado native here, and one who grew up in the sparse northern area where possible I-70 might have gone. Spoiler: there was no reason to have a freeway there. Anyhow, I've driven I-70 countless times and love this little piece on it. Regarding Eagle's Nest, my dad told me a story that the state did take the road planners up to Eagle's Nest in winter to show exactly how much it snowed there and they instantly reevaluated the plans. I imagine combined with concerns about the environment impact, the snowfall thwarted the plans. I've also gone over Vail Pass in heavy snowstorms. The grade is such that a car with front wheel drive and good tires generally is going to be fine (assuming you're wise enough to go slowly and carefully). But I've also had to wind my way around jackknifed trucks and SUVs with balding tires. I no longer live in Colorado but I still hear the stories of ski traffic on the weekends making the journey back to Denver an hours long ordeal. Highway planners don't have many options to expand it. I don't envy their jobs!

[@kimball_stone]

Having grown up a Colorado mountain kid, I have driven 70 an uncountable number of times, and thus very much appreciate this excellent explanation of it. Could've used a skosh more about the design of Glenwood canyon, but whatever. Still very much into this video. Nice work.

[@scubarubanzaii]

I-70 is an INSANELY impressive drive, road wise and scenery wise. I’ve only ever been through there in a semi truck, but I recommend everyone tries to drive it sometime.

[@Oooooooooz]

As someone who goes through this road often, what’s just as crazy is the section in Utah. There’s absolutely NOTHING there. If I remember correctly it’s something like 100 miles with no towns, gas stations, etc.

[@CharlieOsmar]

Used to regularly make this route going from Denver to SLC. Its a great little stretch on a looong drive that i used to look forward to. Thanks for another interesting video!

[@scottanos9981]

Once you go over soldier summit to join up with i70 just past Price, the real journey begins lol

[@alymae1318]

Thanks for the great video ❤ I drive Denver to grand junction and back at least 5 times a year and see so many accidents, snow or sun… But you also see so many sides of Colorado and I am nearly in tears every time I have the opportunity to take this breathtaking drive. I’ve lived here for all my 26 years and I see Colorado different each time I drive I-70

[@hweigel528]

I'm beginning to think Sam might secretly be a Colorado ski bum, every other video is about some sort of mountainous CO logistics problem haha

[@andrewsteavpack9079]

He is! I don’t think it’s a secret though based they’re based in the roaring fork valley (Aspen)

[@ShadowRaptor8]

He's a Coloradan. I've watched him for years but didn't realize till he did his video on power grids. I remember when he posted about grocery stores and showed a King Soopers in B-roll and I'm like "hold up I've been there"

[@BruhMoment-mn9kn]

Absolutely. Fkn. Based. Those Civil Engineers were absolute legends for managing to build so well with such elevation, and keeping the overall landscape (relatively) intact.

[@MainlineThruTheRockies]

I-70 sadly ruined a lot of historic Railroad grades, including the famous Colorado and Southern Clear Creek narrow gauge branch, which included the super famous Georgetown Loop. Luckily they save the Loop, but the rest of the route was destroyed and paved over 😢

[@NickD388]

Great Video!! It's easy to take for granted the impressiveness and complexity of a road so convenient. I travel frequently and 2020, 2021, and 2022 made me truly appreciate the convenience of I-70. Many days I worried I wouldn't beat the thunderstorms forecasted for Glenwood Canyon and I'd inevitably be stuck in Dotsero or forced to traverse one of the hours long detours to get home. I-70 is a true marvel of engineering and holds untold convenience and value to not just those who live around it but to the country as well!

[@R2debo_]

You need one brick, one wood. catan reference.

[@paul-morgan]

We've spent the best part of 3 months vacationing in the US road-tripping. The interstate highway system is a brilliant piece of infrastructure and a pleasure to use.

[@bryancorbellini4952]

In the late 90's and early 2000's the state wanted to build an elevated passenger rail line from Denver international airport to Grand Junction using the I-70 corridor. As I recall state voters rejected the plan because it was going to be VERY expensive and only benefit people living along I-70. Still, I would have enjoyed taking the train to the Airport or Downtown Denver from Edwards Colorado instead of driving.

[@Croz89]

It wouldn't have been able to follow I-70 exactly either, rail lines have tighter tolerances for gradients and curvature.

[@darthmaul216]

Some people just do not understand long term benefit

[@johnchedsey1306]

At least the Amtrak from Denver to Grand Junction is a rather pretty, if somewhat slow, ride. I do recommend it for a leisurely, but beautiful experience.

[@jamesdinius7769]

Expensive, and largely pointless, since the California Zephyr already runs from Union Station to Grand Junction. The only gap was from DIA to Union Station, which is now covered by the RTD A Line.

[@jamesdinius7769]

​@@johnchedsey1306It would be a monumental undertaking to get a rail to go faster through those mountains.

[@Archsponge]

Just moved across country a couple of weeks ago and just experienced this drive on this beautiful and thrilling drive! I was impressed by the Glenwood Canyon segment and the fact that the tunnel was almost as high as the tallest mountain I’ve ever HIKED!

[@Archsponge]

Coincidentally, I took the tunnel at the highest point in the entire Interstate Highway system to move a mile away from the lowest tunnel in the entire Interstate Highway system (Fort Mchenry tunnel in Baltimore!) 😆

[@daveandrew589]

Imagine how much different the Colorado Ski industry would be without the Eisenhower tunnel and Vail pass. I'd be happy if I-70 went underground at Golden and came out at Glenwood Springs. But I don't have the $50 billion or so that would require.

[@DarkHarlequin]

I love the Wendover / Half as Interesting Synergy where Wendover shows us "look at the amazing feats and complexity behind our modern world! See what we can achieve as humans!" and then Half as Interesting videos going "and now that you're marveling, look at all the things we royaly f***ed up in this modern world, mostly because laziness and stupidity!" 😄 You're doing great work Sam & Team 😄

Absolutely fantastic video. I love that road, and I'm thrilled to see some of what it took to build it. Thanks for the time and effort on this one! Keep up the great work.

[@Kuj]

In the 5 years I've lived in Colorado I've pretty much been in all these situations including the tunnel closures, mudslides, avalanches, boulders in the road. I don't even travel along the I-70 more than 5 times a year. There was even one time in 2021 when I was travelling with another group in the car behind us and fears of further mudslides caused us to be last car through and they stopped our friends behind us. It took them 5 hours before they were able to meet up with us. It was wild being the only car on the road through 30minutes of driving on the I-70 and lots of excevators cleaning up mudslides while we were driving by. Another time coming back from ski resort in the snow, a 2 hour drive took us 10 hours... It's a wild yet beautiful stretch of road. The very first two shots of your videos were where the mudslides are usually the worst!

[@alec7501]

Great video. Never been so interested in roadworks, and it’s videos like this that trigger my interest in engineering and architecture.

[@maxenielsen]

Highly informative! I lived in the Denver area before the Eisenhower tunnel was completed. Loveland pass was indeed challenging during the winter. Along with the challenge, a lot of the mystique and beauty went away, too. It seems almost too routine, except the tunnel and its setting retain elements of marvel and awe. Glen wood canyon is another matter. I miss the two-lane days. The canyon seems irretrievably gone. Certainly the though-time is much shortened. But the romance and beauty are gone. And problems continue. Thanks for the very well done presentation!
