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:

    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.

    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 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

    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 KZread 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!

    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...

    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.

    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.

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.

    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.

    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".

    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.

    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.

    +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.

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.

    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 KZread 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. I did actually visit your site for my other video about the Road Zipper -- hope I got that one mostly correct. Thanks for the comment, I do appreciate it.

    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

    @PartyOfTheThirdPart

    8 жыл бұрын

    +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.

    +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.
