Golden Gate Bridge moveable median barrier installation: closeup and narrated (January 10, 2015)

Take a stroll across San Francisco's Golden Gate Bridge with me as we watch up close the assembly/installation of the new "moveable median barrier" (MMB), including the insertion of the final center segment. I have no association with anyone in this project - I have no inside knowledge - so I apologize in advance if there are any technical errors in my narration!
This new Moveable Median Barrier (MMB) system is about 13,340 feet of 12-inch wide and 32-inch high steel clad units filled with high density concrete pinned together to form a semi-rigid median barrier. There are also two barrier transfer machines, aka “zipper” trucks.
This replaces, and is a vast improvement over, the old plastic pylon divider system, which we review for a moment at the beginning of the video.
You can see the Barrier Transfer Machine, that moves the barrier, here:

He comments that the bridge has never been shut down for construction. I don't know about that but in the eighties it was shut down for bad weather. There had been mud slides and the highway was closed. But they forgot about the on ramps from the military housing in the Golden Gate Recreation Area called Ft Barry. I lived there and left in the morning to go to work at Letterman Hospital. Our usual exit from Ft Barry through a one way tunnel was closed by a mud slide so I took the other route which was over the top, a scenic windy road. It was open and as I got to the bridge it was completely empty including of course pedestrians. I was the only one on the bridge and as I crossed I heard a reporter in a helicopter report on the radio "It looks like the bridge might be opening. I see a car crossing the bridge." It was me but they weren't opening it until the next day. The best part was even though the bridge was closed, the ticket takers were in the booths to take my ticket. Thanks for this story.

The comment I was looking for! Thanks Martin Nation!

[@warrenfowlie1608]

Congratulation to the Golden Gate District of Caltrans for the hard grind of over 20 years, to get the barrier onto the bridge. Having worked on the replacement MLB for the Auckland Harbour Bridge here in New Zealand some 5 years ago, I understand the benefit of this important roads safety device. The users of the GG bridge now get the very big benefits of not having to worry about head-on crashes. Need to also say that Barrier Systems; the manufacturer of the system, are a great team of people to work with. Well done to all concerned. Sorry, forgot to mention. HD video is excellent. For being an outsider looking in, coverage was very professional and informative - well done //waf.

The first ever that came to operation was utlized in Boston Dorchester Quincy 93 express way in Massachusetts. This type of divider aka "zip line" not only partition the road but also will help to add and change the amount of lines available on each side of the traffic based on time of days and amount of traffic. Very smart solution to help ease the rush hours traffic indeed. Nice video.... Thank you

[@busdriverbob8977]

Your video here just became one of my all time favorites because it falls into ("It's a Small World") category! - Because 2 minutes and 33 seconds into your filming, you captured two Northbound Golden Gate Transit buses crossing the bridge. Bus# 915 was behind #1521 and the driver of #915 was Bus Driver Bob (me) with a camera sitting on the dash capturing the video now on KZbin under the title (Crossing the "Closed" Golden Gate Bridge during 2015 Construction - Driving Golden Gate Transit) I am going to try to go back and see if I can spot you recording there on the bridge as I rolled by! - I really enjoyed your entire video and saved it to my favorites. I've now Liked & Subscribed to your channel and I'll let people know to check out your video..... What a trip!

[@PartyOfTheThirdPart]

Bus Driver Bob You are quite correct! In today's world, where every event has a million people recording from every angle, it is inevitable that they will each be in each others' video. I did indeed spot myself in your video, but only because I know what I look like -- you can only see me from behind and for a couple of frames and you can't see my camera, so only I know it is me! This is actually not the first time something like this has happened. I often record events in SF, and there are others who do the same and on occasion I have been able to spot myself in the background of one of their videos.I actually thought about taking a GG Transit bus that day, but never got around to it. I did take a Muni 28, but not GG Transit. Occasionally I do drive-lapses and train-lapses, and I've thought about doing bus-lapses -- who knows, maybe we could collaborate on a bus-lapse someday...

[@RaymondHng]

+Bus Driver Bob: Haha! Same thing happened with a segment I edited of a rally/counterprotest at Portsmouth Square. A second cameraman who was there posted his footage on KZbin and I found my cameraman captured in the second cameraman's footage. So I went back through my cameraman's footage and found the second cameraman captured in our clips.

[@peggyt1243]

It is a copy of the Auckland Harbour Bridge in New Zealand which was the FIRST. BELOW IS A DIRECT QUOTE FROM WIKIPEDIA In 1990, a movable concrete safety barrier was put in place to separate traffic heading in opposite directions and eliminate head-on accidents. Two specially designed barrier machines moved the barrier by one lane four times a day,[28] at a speed of 6 km/h. It took 40 minutes to move the barrier, which was the first of its kind in the world. en.wikipedia.org/wiki/Auckland_Harbour_Bridge Yes folks, the USA is 25 years behind New Zealand when it comes to zipper lanes and moveable barrier machines known as road zippers.

[@MAVA1686]

+peggyt1243 this barrier is of metal not concrete.... soo it is a Movable Steel safety barrier ....and i think it will be more durable ..... if it is a copy I don´t know. and i dont know if you were angry .... XD

[@peggyt1243]

+ma va My issue is the USA claiming they are first. They are not the first to have a zipper lane.

[@MAVA1686]

ok . I understand you.

[@JonathanRossRogers]

Who claimed the Golden Gate movable median barrier was the first one? I heard no such claim in this video. This video starts out saying that people having been talking about putting a movable median barrier on the Golden Gate for many years and that the video is documenting the first time the Golden Gate has had such a barrier. The wording implies movable median barriers have existed elsewhere before.

[@Matt68B]

Awesome, I've never seen such a barrier before!

Great video! 👍 Really enjoyed your humorous narration. You have a very, very nice voice.

[@PatrickWagz]

Thanks for sharing, this was fascinating. It looked like quite a few of the sections were adjustable length-wise. That poor guy needs a bigger hammer.

[@MrPLC999]

The whole engineering problem at the end could have been eliminated if they had started assembling the barrier from the center outwards. Seems like an obvious solution to an obvious problem.

[@MarkFunderburk]

MrPLC999 my thoughts exactly.

[@jeffsloop4123]

MrPLC999 Yup, I was thinking the same. You can still work twice as fast as starting from only one end but you don't have to worry about lining anything up.

[@inactive67]

+MrPLC999 The point of the dividers is they are movable to allow more lanes for rush hour. They have those expansion joints every 20 sections or so because if they did not they would not be able to move the divider to the adjoining lane within the length of the buss size equipment used to move the dividers. Google zipper lane divider

[@radiorob7543]

+Jeff Sloop These are State workers. They don't know what fast means. One of many reasons why California is going broke.

[@Maloy7800]

And after they're done, they watch the drone video, drink beer and say, "YEAH, we held traffic on the busiest city artery for a whole day. The day went well!". And laugh.

[@1topfueldrag]

while it’s closed it looks like that would be a good time to do some paving work. Nice vid

[@dw75002]

In reference to the bridge never being closed for construction, there have been closures when they were re-stringing the vertical suspender cables. They had a machine that climbed up and down the main cables, and they had to close the bridge for a few hours when they moved the traveler from one section of the bridge to the next.

[@PartyOfTheThirdPart]

dw75002 Various news reports at the time made this claim. The claim was that it had never been completely closed for construction, only for various celebrations. I can't vouch for the accuracy of those reports, as the bridge has been around longer than I have ;)

[@gatekeeper368]

Party Of The Third Part I was there when the traveler was moved from one side to the other during the restringing operation. Yes the bridge was completely closed in the middle of the night.

[@PartyOfTheThirdPart]

gatekeeper ' Thanks for letting me know! I'd fix the video if I could, but KZbin doesn't allow in-place replacement. I'll see if I can put something in the annotations (for those that can see annotations).

[@riiwind]

That fork driver is useless.

[@MrCowboy1492]

Why did not they start in the middle and go to the ends...adjustments would have been easier. Also, THANKS for posting, I love watching all sorts of construction. I just wonder what's the bottom made from...dragging it across the lanes won't it tear up the bridge and then they have to close it to repair the damage. Will they paint the steel parts so they don't rust. How long does it take to move the entire barrier. I think someone should climb to the top of one of the towers and base jump with a wing suit....yeeehaaa..Thanks again for posting.

[@Captain_Coleslaw]

The last piece from the north side is extendable, so it would always fit no matter what they did

[@theyruinedyoutubeagain]

I'm an engineer and I didn't even consider that lol. Good catch

[@jaypom1513]

That second to last piece is actualy telescopic. They would never have had to redo all of one side.

[@lifesavrdwd]

Thanks for the video, it was surely well done and informative. I can't believe they don't have a jig that allows them to pickup and move one of the barriers from its side. Strange. I wonder about the added weight to the bridge. I must be a lot, though it is spread across the whole span.

[@PartyOfTheThirdPart]

+lifesavrdwd Thanks for the comment I appreciate it! There are a couple of us who have speculated about the weight elsewhere in the comments for this video.

[@joek0617]

+lifesavrdwd nah. the maximum each set of 2 could possibly weigh is only 3200lbs, based on the jig's warning marker.

[@ShipSpottingNederland]

[@Gamerz00760]

I am wondering when tow motors semi trucks and cranes wil get cameras to view in front and behind. It would be much easier if operators werent blind the entire time and going by voice guidance or trying to guess.

[@NicholasLittlejohn]

The master link looks to be adjustable, even up to part of the full meter :)

[@firstnamelastname7143]

Interesting, @12:38 to 13:24 you can clearly see the end on the right is a special sliding link to allow for adjustment installing the last section. What is the purpose of this being movable, to allow for an extra lane one way in morning traffic to work, then the other way heading home?

[@readysetsleep]

+firstname lastname Yes switch it to 4 lanes in and 2 lanes out morning rush hour and 4 lanes out and 2 lanes in during evening rush hour. Here in NYC to NJ they use the 4th lane for buses, but they don't have a fancy barrier system. Just the cones and pegs, kind of scary for guys to move them during full traffic.

[@judithfenske2311]

Military bases and D.C.use the closing of lanes in rush hours. Works very well.

[@YuiHellshire]

when they drop the barrier, watch in the back ground the bridge does move a little.

[@gerry343]

$30 million? What's it made of, solid gold?

[@fimbles1015]

So now it even narrower?

[@xl000]

At 11:05 one guy lift a barrier with a 3:1 mechanical advantage. At 5:35, you're claiming each piece (pair) weighs about 1550 pounds, or 700 kg. That's 775 pounds / 350 kg per barrier.. I don't know... that looks like a lot to casually lift 120 kg (or 90 kg with a 4:1 mechanical advantage), given that he looks like an average built person. If someone can have a look at the physics behind that

[@martintorrez25]

It's always great to see CalTrans workers actually working. LOL

[@BobSmith-mc7uq]

You mean the fork lift driver & the hammer man? All the rest were supervisors & office junkies out to get on camera.

[@ganeshrvgk]

Did any one calculated about the weight of the barrier which is left on top the suspension bridge. Is there any impact on the bridge stability. Although the traffic on the bridge is counted, but it is an moving traffic.

The bridge is 2,737 meters long, so obviously they go beyond just the bridge itself and include some of the approaches on each end.

Are you f.ing kidding me? I hated driving on the GG. I was already creeped out enough by just driving on the bridge but then worrying about oncoming traffic was a nightmare. I still hate driving on the Bay Bridge though. I hadn.t been driving long when we were hit by Loma Prieta and I know that my fear of driving on either bridges is related to that. If I have to go to the East bay, I take bart. I rarely,if ever, drive on the Golden Gate but if an occasion calls for the North bay, I make someone else drive while I freak out in the back seat.

[@geomodelrailroader]

once the barrier is installed it will be ran over with a zipper truck to move it into its final spot.

[@kingmike40]

At 13340 ft long and each piece being 3.28 ft and weighing 1550lbs that comes to 6,303,963 lbs that is on the bridge all of the time. I wonder if they took in to account the wear and tear of the bridge, but if guess there really wasn't another option.

[@MegaFakedude]

+kingmike40 The company that built this system, Barrier Systems, was purchased by Lindsay. Barrier Systems was formed roughly 20-25 years ago for the primary purpose of putting this system on this bridge. It's taken that long to get all the approvals and funding. In that time, though, dozens and dozens of these systems have been deployed throughout the world. You can be sure that the bridge engineers had hundreds of hours of discussions of the extra weight. Take into account, though that cars are getting much lighter. We have priuses and Leafs now, not Oldsmobiles and Buicks.

Scary? Has this man never driven on a two-lane highway? I know of some fairly narrow two-lane highways that have a speed limit of 75.

[@PartyOfTheThirdPart]

Jordan Saylor It was a little scary because the lanes are narrower than standard, there are no shoulders at all, the markings of the lanes do not distinguish in any way the directions (there are only white dots that are the same in every lane), there are no lights above the lanes as many places have to show the direction of travel, and the lane configurations change at different times of the day. So other than the little widely-spaced plastic pylons, that are difficult to see, especially at night or when there is thick fog (which is very common on the bridge), there were no visual clues as to which lanes were for which direction, and the configuration is different at different times. What was most scary was relying on all other drivers, including people from out of town and "impaired" drivers, to handle this situation correctly. Also, those narrow roads you're talking about are typically one lane in each direction. On the bridge, there are 6 lanes. So when you're in that left lane, if someone in the 2 or 3 lanes to the right of you makes a mistake (because they're a tourist gawking at the bridge) or has a mechanical problem (such as a semi blowing a tire), and swerves into you, there's nowhere for you to go, you're going into the opposing traffic because it is only 12 inches away and there was no barrier. And the bridge is very busy, so you're not going to find an empty spot, you will have a head-on collision. This is why the leftmost lanes on the GG bridge were widely known in the Bay Area by the nickname the "suicide lanes".

[@buddyclem7328]

Where is there a 2-lane highway with a speed limit of 75MPH? In the United States, the highest, non-interstate highway speed limit is 70MPH, in Ohio, only for 4-lane divided highways.

[@chrissanders3047]

Nice job overall . I am the manufacturer and I am now wondering why I hired those expensive professional photographers. One minor correction the barriers are 1 M long (3.28 feet) and weigh about 1550 pounds each. Come visit our website at Lindsaytransportationsolutions.com for more technical details.

[@PartyOfTheThirdPart]

Chris Sanders Thanks. I'm sure the professionals can do things I can't. I try to make my videos entertaining, sometimes with a "twist" if possible. My advantage over the professionals is that I can throw away the ones that don't work out and nobody ever sees those. Although... next time you have an interesting project in SF, maybe we can work out some sort of access ;) No charge on either side! ;) Thanks for the correction -- unfortunately with KZbin there's no way to replace or update a video. I can add some annotations with corrections, although annotations don't work in all environments and people turn them off too.

[@PartyOfTheThirdPart]

+Mat Tuk Here is a newspaper article about the project, in which it is stated: "The barrier will be made of more than 800 blocks that weigh 1,500 pounds each. " www.mercurynews.com/california/ci_27273680/new-zipper-trucks-golden-gate-bridge-will-move

[@peter_smyth]

The barriers are made of steel, and I think are filled with concrete after installation by the hose connected to that thing with wheels being slid across the top of the barrier.

[@PartyOfTheThirdPart]

+Peter Smyth The barriers are already filled in with concrete when they are installed. The wheeled thing that goes across the top aligns the segments properly and then drives the connecting pin between segments in the rest of the way (the guy with the hammer only starts the pin going, hammering it only part way in). The segments are heavy, but have a relatively smooth bottom and three strong men can slide them a little bit at a time across the relatively smooth pavement. But it takes a lot of effort and they don't do that often.

[@peter_smyth]

+Party Of The Third Part I was wondering what that does, and how the pins got fully inserted.

[@MegaFakedude]

+Mat Tuk The thing they are moving is a VLB (variable length barrier). This is hollow steel. They place these every so often to accommodate the expansion and contraction of the barrier as it changes positions. As you can imagine, the barrier changes length as it goes through the machine. Anyways, it's not 1500 lb, as you guessed. Maybe around 500 or so.

Ah true. I didn't think about the cost of the road zipper being included + construction costs + planning costs. They could probably even estimate lost tolls due to closures. I guess $30 million would make sense.

+Dondrey Taylor I think each zipper truck costs $1.4 million.

+Dondrey Taylor $30 million sounds reasonable, considering..... The new east span of the bay bridge originally was projected to cost $800 million, then just over $1 billion. It ended up costing $6.4 billion. And, it is cracking and at risk of failing. Projects like this cost fortunes to please unions and political supporters. They just throw the bill at taxpayers who have no choice but to pay high tolls. Only San Francisco and Oakland politicians can spend other peoples money like is flows in with the tide. Los Angeles has their subway. Another taxpayer funded boondoggle. Minimal tolls lost and minimal construction costs. Just the Road Zipper machines and the blocks at about $5000 per foot.

Mark G Wow, thanks for the break down. I had no idea they spent this much on these types of projects.

[@mikepratali5582]

yes, please correct your facts. It has been closed before... high winds, pavement, earthquake damage/integrity. it's been closed many times.

+Mike Pratali Unfortunately, KZbin provides no way to edit a video in place, so I can't make any changes. However, I didn't state that it had never been closed, in fact I did say that it has been closed before, I only said that it had never been *completely closed for construction* before. Which is almost true. Turns out it was completely closed for construction one other time in the past. So I was off by one. My apologies, for that, but I have no way to change it.

+Party Of The Third Part Why, yes you did. You have a great monotone voice for narration and I appreciate the time and effort you used to cover this story. Did you know of the elevator in the North tower, or how there was a group of people you could hire to hike you to the top of the North tower. That is why they installed personal barriers that can be see just off the ground on the North side???? Thanks again for the coverage..
