Why You Have NEVER Heard of These Highways | America's HIDDEN Interstates

[@washuotaku]

I dislike when state DOTs hide highways like that. They do the same towards U.S. Routes too in several states and its not necessary. If they want less confusion, reroute them.

[@ki5aok]

My biggest pet peeve with hiding highways is that, sometimes it isn't necessary. Case in point: US-90 through Houston. On the east side, US-90 merges with I-10 at I-610, and on the west side it is an exit in Katy. Between those two points, there is no signage for US-90...it's just I-10. It's like US-90 has some weird gap in it. It didn't used to be like this. When I moved to Houston in 1980, there were signage all over the place showing I-10 and US-90 together through Houston. I could be wrong, but I want to say that the US-90 shield started disappearing when US-75 was decommissioned from Dallas to Galveston. My surprise is that TxDOT hasn't removed the US-59 shields from signage now that the road is I-69 (although at SH-99 Toll / Grand Parkway in Porter, Texas, they installed signage with only the I-69 emblem...no mention of US-59).

I live in Dallas and have traveled on I-345 many times. I've never understood why they didn't just extend I-45 to US-75, or better yet, extend 45 all the way to Oklahoma. I suppose at some point 75 isn't up to Interstate standards, but within the DFW metroplex, it all feels like one continuous expressway.

[@arnathan1792]

Yeah it’s basically interstate standard up until the OK border. They could run it up the Indian Nation Turnpike to I-40 after the south Oklahoma section is upgraded to interstate standard. I would like to see I-45 go to Topeka and possibly Omaha

[@ki5aok]

@@arnathan1792 The road around Sherman and Denison is still below current Interstate standards, but, from what it looks like on Google Maps, TxDOT seems to be trying to rectify that issue. And it also looks like Oklahoma (or the Choctow Nation) is building interstate segments of US-75/US-69 to Durant. As for I-45 going to the Oklahoma border, I don't see why not. Wisconsin pulled that with I-41, ending it at the Illinois/Wisconsin border. As long as US-69 isn't decommissioned from Denison to the border.

[@perrylykins5518]

Yep. There is construction near both sides of the border. So from Dallas to Tushka, OK is up to highway snuff. But from there to just North of McAllister. Is only state highway quality. With stop lights in most of the small towns. You'd have to elevate the roadway through towns like Atoka, Stringtown and Kiowa. Kind of like they are currently doing in Calera. Just south of Durant. Or risk cutting those small towns in half. Also. I've lived in the Metroplex for almost 14 years now. And never knew about this highway designation. I always thought it was just the start of 75.

[@ix830]

75 and 45 feel like two different highways with different purposes. It'll be interesting how closely the 345 redo resembles 75

[@jerodstanley3752]

An extended I-45 could serve as another cross-country trade corridor if connected to I-29 in Omaha via Tulsa and say Topeka and also be a more direct connection for the port of Houston to Canada rather than having to go through Kansas City.

[@TravisWilliams3333]

I find it interesting how US 50 is the only route in the entire lower 48 that is home to TWO unsigned interstates. As you mentioned, I-305 in Sacramento and I-595 in Maryland

[@danieljackett4193]

Back to Grand Rapids When the Interstate System was originally funded, I-96 was supposed to follow what is I-196 to Benton Harbor, and I-196 go to Muskegon...The contractor built a segment of both highways together, causing motorist confusion when the shields went from 96 to 196, and vice versa...Also the US route (16) the Interstate replaced also went to Muskegon...So the 96 and 196 designations were flipped, making I-196 the longest 3-digit Interstate at 80 miles

[@Markkos1992]

I guess that was the case at that time. Obviously I-476 (and others) are longer now.

[@olegfedorov9171]

I’ve driven through Chattanooga on us 27, I remember when they rebuilt it when I got older and now it kinda does look like an interstate but I have stumbled upon an article online where this was unmarked interstate I-124

[@GarrettWorcester]

US Route 50 between I-95 (Capitol Beltway) and Annapolis (I-97) was signed as I-595 "for a minute," as the kids say today, so that explains why (as you stated) there's still a significant blank space on the signs over the highway. I even wrote an accident report or two using the I-595 designation instead of Route 50... no one noticed.

[@Markkos1992]

I actually clinched I-595 in FL in 2009 about 12 years before clinching I-595 in MD in 2021 even though I have always lived much closer to the latter.

When National Weather Service releases a severe weather statement map it sometimes shows the I-595 because the only roads it shows for reference are interstates.

Interstate 595 was never signed in Maryland due to "branding" - especially between the DC - Maryland border to the Severn River Bridge - US 50 is the predominant brand.

[@tomsmith5584]

One that you missed was I-480X southeast of Cleveland. It connects US 422 and I-271 with I-480. It forms the northern part of a triangle with I-271 and I-480. It probably wasn't signed because it is fairly short, about 2 miles, and might confuse motorists in an area with a lot of freeways. The only signage is on the mile marker signs in the middle of the highway as it has no other route number.

[@ki5aok]

The reality on this is that I-480N should have been decommissioned and US-422 should've been extended until it met with I-480.

[@Markkos1992]

@@ki5aok I think you can justify having the western terminus of US 422 being at the I-480/I-480N interchange, replace the current US 422 to downtown with OH 87, and renumber OH 87 as OH 887 between US 422/OH 8 and OH 175 if we really need to keep the Shaker Heights section of OH 87 as a state route.

It's not like I-35W/E in Dallas/Fort Worth and Minneapolis/St. Paul, where both of those examples serve two cities and both merge back together to form I-35. I-480N is nothing more than a long exit ramp. It would make more sense to eliminate that designation (I-480 will still pass to the south) and extend US-422 over that route, for a distance of about 2 miles. Eliminating I-480N does not affect I-480.

It's essentially an overengineered on/off ramp from I-15, but it does serve as a connection to the Great Falls Marketplace plaza, as the only other connection would be a single residential road. It probably just made more sense to have it designated as an Interstate. For the other highways, The Business Loop just goes through downtown and ends at the Central Ave W bridge, US 89's Montana section ends in Yellowstone, Hwy 3 is the highway between Great Falls and Billings, and Hwy 200 is a long, continuous highway that stretches from Idaho to Minnesota - our highway ends at the border of North Dakota, where it becomes ND-200.

I've driven in on I-124 plenty of times. An argument could be made that I-124 actually starts much further north as their is a state road that merges in with U.S. HWY 27 and the road is interstate standard from that point heading across the Tennessee river and straight to I-24

Until 1990, the freeway ended at the US 127 interchange just across the river. The section between TN 153 and TN 319 was built in the mid to late 70s, and the TN 111 section to Dunlap was upgraded to freeway in the early 2000s. The I-124 designation was established in the late 1950s, although the freeway to the north was authorized by the Appalachian Development Highway System, although I don't know that it was originally planned to be a freeway. But that is probably why the designation was never extended north.

There was going to be 2 children for I-97: I-197 and I-297. Sadly, all of that was cancelled and we now have I-595 instead.

[@Goadfish1729]

I-296 actually breaks off from US 131 and runs west towards Alpine Ave / M-37, instead of the way you have it in the video, following north to the 96/131 near-cloverleaf. Back when Google Maps did show 296 it showed the correct routing. Like you said, it is a complex intersection.

[@Goadfish1729]

Also, there are two unnumbered exits on the stretch you missed, due to the road being neither a part of 131 nor 96. One exit is to eastbound I-96 and the other is to North M-37. If this was signed as I-296, would this exit have to be numbered? Maybe that is another element of potential confusion considered when deciding not to sign it.

A simple explanation is that major US highways and Interstates often bypass the central cities.

Often times these business highways are surface streets and not actual freeways.

I sure do miss those fun turns on the old route though! Chattanooga residents know what I’m talking about 😂

[@jakkew5753]

I don't know if the median was an issue, but it definitely didn't meet interstate standards. The curvy section from MLK to the Olgiati Bridge didn't even have shoulders, and this section was designed before the Interstate system was initiated. Now that it's been redesigned, I think they should consider resigning it, but now that there's a continuous freeway for about 50 miles some people would probably want it signed that far.

Fun Fact about I-345 and US-75...US-75, according to TxDOT's highway database, ends at I-345. Here's the description: "Minute Order 085364, dated 01/28/1987; Adm. Ltr. 006-1987, dated 06/11/1987 From the Texas/Oklahoma S/L north of Denison via Denison, Sherman, McKinney, and Richardson to IH 345 in Dallas, a total approximate distance of 79.0 miles. (Grayson, Collin, and Dallas Counties) In a joint request by the Administration and Districts 12, 17, & 18, US 75 designation cancelled from Dallas southward to Galveston." So, technically, US-75 starts at the Woodall Rogers Freeway and continues to the Oklahoma border. I-345 is not multiplexed with US-75 despite what the signage suggests. This also explains why I-345's mileage is a continuation of I-45's mileage and that Exit 1 of US-75 is Spur 366 (or signed TO I-35E on the US-75/I-345 side and TO I-45/US-75 on the I-35E side).

As to cities and states not signing some highways -- There is a small section of I-465 in Indianapolis that, due to INDOT's desire to relocate highways out of downtown, is actually: I-465/I-74/US 31/US 36/US 40/US 52/US 421/IN 37/IN 67 (and let us not forget future I-69). INDOT just places a sign before 465 informing which way to go to follow these highways, and only has 74 and 465 signed.

[@GeoGuy388]

Wow, I lived near US 50 in Maryland my whole life and had no idea it was also an Interstate. Mind blown. You get a thumbs up just for that.

[@rayfridley6649]

Having lived in Maryland, I'm glad that I-595 remains unsigned. U.S. 50's eastern half is concurrent with U.S. 301. Having posted I-595 would be confusing to motorists.

[@MisterVercetti]

One that wasn't covered was I-265 in Louisville, Kentucky, between the I-71 junction and the northern I-65 junction, as well as everything west of the southern I-65 junction. All official signage for these sections are for KY Hwy 841 or IN Hwy 265, though as of the completion of the Lewis & Clark bridge, they all make up a single, unbroken expressway.

[@Markkos1992]

KY and IN are planning to finish signing the rest of I-265 at this point.

I-305 for Sac Town is a 50/50 for me, but lately on Google Street view. The Guide Signs are posted as US 50 from the I-80 to California SR 99. Although, I prefer the Business Loop 80, it's already a Sacramento staple. It also gives the Californian variations of highway shields to identify route markers on its Freeways. Kinda like the East LA interchange, there's the Spade, Interstate and US Federal Shields on the BGS to categorized the Freeway Routes. Perhaps I-305 can be for a new Interstate from I-5 as a new Spur route to Yuba City. Helping to accommodate California SR 20. There are some Freeway Segments in Yuba City. Or even stretch it as far to reach I-80, a new Truck By-pass and avoiding the Sacramento Metro Area.

[@robertlindey2538]

Today's Bus Loop 80 "splits" from today's Interstate 80 northeast of downtown Sacramento and heads southwest. After about 9 or 10 miles, it intersects with US 50/CA 99 in downtown Sacramento. It then joins those other two routes and heads west across the downtown for 3 or 4 miles (this is the unposted I-305 shown in this video). After that, it ends at today's Interstate 80 in West Sacramento. Up until 1982, today's Bus Loop 80 was posted as Interstate 80, and the freeway that "split" in the NE heads north of downtown Sacramento to West Sacramento was renamed to be today's Interstate 80. Until 1982, this freeway was known as Interstate 880. That number was then designated to an Interstate freeway from Oakland to San Jose (formerly CA 17).

Have you done a video on roads that while signed as Interstates, don't meet interstate standards?

[@Clemsonjmal]

When I first moved to the DMV I always thought it was weird that no interstates went to Annapolis on the map. Then I went to Annapolis on US 50 and was like "This IS an interstate 🤷🏾‍♂️" then a year later when I moved to an apartment along US 50 I realized that that route takes you all the way into DC before its no longer to interstate standards. Who knew? 😅 They really should mark that portion as 595

[@boltstrike2787]

There's a reason why they don't, it's redundant. The entirety of 595 is just a segment of US-50, so it would be pointless and confusing. Maybe if somehow becomes discontinuous with 50 they'd bother signing it but for now, no.

[@Clemsonjmal]

@boltstrike2787 You seem very passionate about that for some reason 😂. It just makes it easier to tell what type of highway it is to me. I dont see what could be confusing about it 🤔. Before moving to the area, I looked at a map and assumed the entirety of US-50 was more like a boulevard like on the Virginia side. It was only once I moved there and had been there for a while that I realized it was basically an interstate, no different than 395, 295, or 695 (its actually in better condition than much of I-295 😬). Not saying you're wrong, I just disagree 🤷🏾‍♂️.

[@boltstrike2787]

@@Clemsonjmal It's confusing because if you have too many route numbers clumped on the same road people will have trouble reading the signs and get lost. Best to avoid listing multiple routes if they don't diverge at some point. I don't think you need the distinction to tell what type of highway it is and there are some U.S. routes that are highways anyway and it's hard to tell which ones are up to interstate standards and which ones aren't. You just need to see what direction you need to go and the speed limit. The distinction helps you figure out which route is most recommended for which destination (which routes are meant for long distance, which ones are national, regional, and local, etc.). It's not going to tell you what's a highway and what's not.

[@oogami256]

@@boltstrike2787But then you have instances like I-41 in WI that contradict your thesis. US 41 was upgraded to interstate standards in 2015 and received signage indicating that it is now an interstate. I-41 is fully concurrent with US 41 from the WI/IL border to just north of Green Bay and the route is signed as both I-41 and US 41 simultaneously (along with I-94 or whatever other route is tagging along at any given point). They didn’t have to sign it as I-41 at all, but they did ostensibly to make it clear that it was a fully-fledged expressway up to Interstate highway standards. Or, how about the infamous I-99 in PA that never fails to get a rise out of us Interstate highway nerds? Ignoring for the moment that it doesn’t follow the numbering conventions of the IHS, it is 100% concurrent with US 220. By your logic, it shouldn’t have been signed at all, given it never diverges from US 220 and individuals already used to traveling that route didn’t need a new designation given. So, yes, I-595 could very well have been signed and I don’t buy the official excuse that it would “cause confusion.” If anything, it would make clear what segment of the route is up to Interstate highway standards, which could be helpful for anyone planning a trip through the area.

[@rayfridley6649]

In the Weehawken-Union City area in New jersey, 495 was once posted as an interstate. Later, it was downgraded to NJ state 495. It is an extremely busy highway carrying traffic to and from the Lincoln Tunnel. I think that the Manhattan portion of 495 shows it as an interstate.

[@davidrigoni8231]

So that’s why recently when I was trucking from OK on US 75 down towards Houston the gps had me continue onto I-345. I wondered what was going on😳

[@jimmyboy131]

I am in favor of reducing the number of signs that drivers need to pay attention to. Especially if there are multiple exits and entrances, each one labeled with its own sign. The two most confusing cities I've had to drive in are Grand Rapids and Baltimore. But by far the worst was Baltimore. Twice I've flown into Baltimore, both times at night, and both times my phone's GPS wouldn't work. I don't know why but it just wouldn't connect. So I had to try to use look at Maps to find my way around. But the combination of night time and poor signage/leaning signs/crooked signs, and the snaking nature of the roads made it impossible for me to find my way anywhere. One time I was parked on the side of the road, looking at the map trying to make heads or tails of where I was, and an 18 wheeler pulled up next to me to ask me if I knew how to find a particular road. I laughed and said that I was just as lost as he was. By contrast, I'm from the Phoenix area and much of the streets here are laid out in a grid pattern, which makes getting around much easier. Point is cities need to pay close attention to their signage, including how well that signage is displayed, and how clear road numbers and names are.

[@theonetruerobb4852]

I regularly travel on Maine's "Falmouth Spur", heading up to Boothbay from Massachusetts. Never knew it was a uniquely numbered Interstate. Maybe I'll win a bet or something. It's numbered 495. There are several other stretches of interstate with that designation - Washington DC, Massachusetts, among others. I'm wondering if there's a story there...

[@idriveastationwagon1534]

North Carolina would definitely have hidden interstates signed 😂.

[@twylanaythias]

One other factor: There are only five available spur designations (1, 3, 5, 7, and 9) and four loop designations (2, 4, 6, and 8) recognized under the Interstate System. This is toughest on I-95, which runs nearly 2000 miles (over 3000km) along the eastern seaboard, passing through Jacksonville, FL, Savannah, GA, Richmond, VA, Washington, DC, Baltimore, MD, Philadelphia, PA, New York City, NY, Providence, RI, and Boston, MA (before continuing to the Canadian border) - TEN major cities with only NINE available designations. Needless to say, they were forced to relax the "one designation per route" clause to allow one designation per state, but even this hits its limits in states like Texas and California - multiple major metropolitan areas gobbling up two or more official designations each. Most spur/loop designations for I-80 in California (an east-west route in a north-south state) are taken up by the Bay Area & Silicon Valley alone (including the fictitious "I-238", as they ran out of numbers).

[@boltstrike2787]

Funny that you mention I-95 and not mention how in Maryland alone they've used up every designation except 995. Really going to make designations difficult if they ever construct future interstates in the state.

[@Silver_Turtle]

I'm not totally sure [and possibly totally wrong]; but I think that each state has permission to use the nine designations.

[@boltstrike2787]

@@Silver_Turtle As near as I know, this is correct. Although if an aux route crosses a state border, I think they have to keep the same designation (for example the Capital Beltway in D.C. goes between MD and VA and is designated I-495, that route serves as each state's designation for I-495 so they can't use it for something else). As I mentioned in my previous comment though, it doesn't really matter for I-95 in MD because they've used up every designation except 995 (with 595 being an unsigned route detailed in this video). That might be tough on MD for future interstate projects.

I forgot about the 345 thing. Yea, last time I ran up to OK back in May, def don't remember see any signs anywhere mentioning it, just ending up mistakingly taking an exit just before 30 coming back to H-town because of some confusing labeling in trying to get to 45 but not 30. You sure gotta be careful up there, because there are some weird or not the best labeled spots. Same goes for US 287/I-35 in FW... sometimes they don't mention 287 when telling you which lanes are which hwys, so you wonder if you're at the cutoff yet (where 287 exits 35 and heads toward Wichita Falls/Amarillo). Looks like you were up there yourself, so hopefully you made the trip up 75 to Melissa and the B•I•G Buc-ee's they got there. >>;=) You can't Texas (and now some other states) without Buceeing. One day, you may have to do a vid just on the wildness of that place LOL. Auburn is the newest one I know about, finished being built / opened between Sep '22 when I went to NH and Jun when a friend of mine ran up to PA, and called me from there. Long as 595 in MD is, I'm surprised they don't go ahead and label that one. I get the ones being unlabeled that are a mile or less in length, but for the reason of "driver confusion" is a little bamfoozling. Now what is confusing or dislexically evil, is in Beaumont, TX... they have US 69/96 exiting I-10 in the same area; it'd be so easy to end up on the wrong one. Love your videos man; I've always liked interesting things about hwys, weird signs you see out there, or just odd road-related situations that are kinda funny (or are to my odd sense of humor LOL). Example.. was on US 50 getting from eastern WV to I-79 and there's about a 10mi stretch you go through that little stick-downy part of the end of MD, it'd be funny if you get to the 2nd part of WV and they would have a sign saying "Welcome BACK to West Virginia" >>:=p

I could almost throw a rock and have it land on US 50 about halfway between DC and Annapolis. I end up on that road to get almost snywhere.

I used to commute on GA 400, which is also inrerstate quality for tye southern 30 or so miles, but does not have an interstate designation. And ive driven on US 285 between Santa Fe and Pojaque which is currently interstate quality, but also not a part of the interstate system. Given my experience with GA 400 and US 285, finding a highway that is interstate quality, but not a part of yhe interstate system was hardly surprising. This video surprised me eith the fact that US 50 here is a part of the Interstate system. Another thing I notoced is that US 50 near bith coasts appeared in rhis video.

I've traveled on Business-80 in Sacramento and never knew it was also designated I-305. I've known of a few cases were people got confused and took I-80 instead of Business-80, or vice versa, in that area. Renaming Business 80 to I-305 would make things clearer, IMO.

[@jimonthecoast3234]

it makes more sense if you explain the numbers are connectors. ex.. 305 in sacramento. connects with US 5 ( NOT California state highway 99 as you claimed ) similarly the 805, the 405 also link up to 5. similarly the 280 in San Francisco, connects with US 80. the first number if it's even, both ends connect to an interstate ( or circles a city ), if it's odd. just 1 end connects to an interstate known as a spur. so 305 in sacramento is a spur route, that connects to interstate 5

You just brought to mind a memory as to the confusion caused when these highways "turn into" city streets for a stretch before continuing on as being called "highway this or that". When I was doing a "sign-holding" job for a store, the employee told me to stand on the north west corner of "36" and so I actually walked down 10 blocks only to discover that after 34th street, there was no 36th street but just a long stretch and then 38th street. I ended up standing midway between 34th and 38th and set up camp there. I thought it was rather strange being so far away from where the store was. Later I found out from a fellow sign-holder, that the employee had meant highway 36, which was 28th street a street a mere 1000 feet or so from the store across the parking lot. Don't laugh, LOL.
