  • 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.

    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
      @PartyOfTheThirdPart  9 років тому +5

      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 UA-cam 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.

  • @MrCowboy1492
    @MrCowboy1492 8 років тому +5

    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.

    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

  • @nameinvalid69

    very interesting. Really wish such system is used widely and there's option for lower cost version.
    it's really stupid to see one side of road is full of cars and the other side is completely empty during rush hour.
    movable barrier is brilliant.

    • @inactive67
      @inactive67 9 років тому

      +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

    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?

      +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.

    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 UA-cam 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
      @PartyOfTheThirdPart  9 років тому +4

      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...

    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

    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.

    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.

      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.

    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.

    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
      @PartyOfTheThirdPart  9 років тому +1

      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".

      There would likely be "heave ho" linking the barrier up to the permanent barriers at both ends then.

    i'm questioning about them pieces are what he said 1,550 lbs each .... @ 8.10 min into this (3) men drag one over into place..
    i don't believe that would be possible as each man can't move 500lbs like that

    • @PartyOfTheThirdPart
      @PartyOfTheThirdPart  8 років тому +2

      +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
      @PartyOfTheThirdPart  8 років тому +2

      +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
      @peter_smyth 8 років тому +1

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

    • @MegaFakedude
      @MegaFakedude 8 років тому

      +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.

      BackyardWoodworks Crafts & More Good question! I read a news report that said there are 3,517 segments. Each segment is 1 meter long, but I don't know if that includes any gap between segments. 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.

    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.

    • @dondreytaylor8001
      @dondreytaylor8001 8 років тому

      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.

    • @peter_smyth
      @peter_smyth 8 років тому

    • @idadho
      @idadho 8 років тому

      +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.
