Golden Gate Bridge Road Zipper in action at the tail end of its morning run

Some closeups of the Barrier Transfer Machine (BTM) repositioning the new Moveable Median Barrier (MMB) on the Golden Gate Bridge at the tail end of its Thursday morning run on January 15, 2015. It started at the northern (Marin) end and this video is of it reaching the end of its run at the southern (San Francisco) end, near the toll plaza.
The 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 two barrier transfer machines, aka “zipper” trucks.
This replaces, and is a vast improvement over, the old yellow plastic pylon divider system, which you can see still in partial use here to block off some lanes at the toll plaza.
You can see the installation of the barrier itself here:

The movable median barrier system allows the use of four of the six lanes into The City in the morning and then four of the six out of The City in the afternoon to improve traffic flow. The previous system of pylons resulted in 16 deaths from head on collisions from 1968 to 2015.

[@sharkheadism]

I lived in SF for 30 yrs. Every now and then, once or twice a year maybe, there was a horrendous head-on collision on the GGB because there was no physical barrier between the traffic lanes. They used rubber day-glo cones which were shifted manually twice a day for morning and evening rush hour. Every time there was another collision, there was a lot of talk about what to do about the problem. I'm glad to see a solution has been created.

I go over that bridge every day and this thing is a life saver. Brilliant to be able to add a lane to one side based on rush hour patterns. In the morning, southbound is one lane wider. Around 4pm they begin to give that lane to the northbound side.

[@Patrick94GSR]

Memphis used to have lanes that changed direction on Union Avenue, using electronic overhead signage. 6 lanes, 4 west and 2 east in the morning, 3 & 3 mid-day, and 2 west/4 eastbound in the evening. It was a NIGHTMARE until finally they just removed them all and made it 3 lanes each direction all the time in the early 2000's. Each lane had a sign overhead every few hundred yards with a green arrow or a red X. It was truly awful trying to drive on that road.

[@EdDeezNuts944]

Art Vandelay I had these on my daily commute over Teddy Roosevelt Bridge (from Virginia to DC), and while it was handy, it was also super nervewracking because part of it went around a curve, and the barriers extended 1/4 of the way into your lane on that curve. You just had to be extra mindful of somebody that might be next to you. I also just hated driving 60 mph merely inches away from concrete barriers (so I often went to the next lane)

[@timenglert8998]

The underlying issue is that the GG bridge is five lanes wide so it's a way to get three lanes for the heaviest traffic flow during commute hours. Way safer than the old method of a guy sitting on a truck moving rubber cones twice a day. I once saw a guy make a three-point U-turn in the middle of the bridge, a miracle nobody was killed.

[@ondrejsedlak4935]

Many people are complaining about the ridiculousness of this system, saying things like "people can move them by hand" or "just use overhead signs". In terms of people moving them, how exactly will those people be protected from high speed traffic zipping along a road which has pretty much no escape areas, not to mention walking the length of this thing without ANY form of protection. As for overhead signs, that works fine for a normal road on which cars have room to pull over safely (maybe on a sidewalk or nature strip), have access from side streets for tow truck or emergency services. All it would take is one tired driver not paying attention to the overhead signs, causing a multi-car pile up with possible fatalities. Any kind of collision on a bridge this size will cause traffic jams for kilometers and make it very difficult for emergency serevices to get to the accident site. Short of building an extra lane and erecting a permanent barrier down the middle, this is the best solution.

[@hiz24airness]

Yeah your theory about overhead lights not working is kinda void consider thats the system we use through out Australia without incident, the sydney harbour for example has no sidewalk or nature strip or access from side streets. This is just straight up dumb, expensive and over-engineering for a simple problem.

@@hiz24airness Sydney Harbour Bridge length: 1149 meters Golden Gate Bridge length: 2737 meters That’s almost three times the distance, which would make emergency vehicle access a veritable nightmare in the event of a major crash.

If you have driven on the GG Bridge that was built in the 1930's, you would know that the six driving lanes are very narrow and the only barrier for decades were cones. Numerous head on accidents have occurred. The MMB is a reasonable alternative even though it takes more footage out of the 'two center lanes'.

[@joestewart8914]

The old 2-mile-long Tappan Zee Bridge in NYC used these zippers for many years. In the morning 4 lanes inbound, 3 outbound, in the evening the reverse. The moveable median wall employed two barrier movers working together, each moving the wall half the distance. The new Tappan Zee bridge opened last year and I'm not sure if the zippers are still used there.

For all the comments about money...if you can increase traffic flow, you can get more people across, which more pay the tolls that then pay for the zipper.

[@Julia_and_the_City]

Certainly would be easier, no doubt, but if dashcam video's on KZbin prove anything it's that some drivers' attention spans are short and warning signs or traffic lights go unnoticed... If only one car driver either doesn't notice the lights or thinks it safe to overtake a car using the switch lane, the consequences of a head-on-head collision at 100 kmph (60 mph) could be disastrous. Best to be on the safe side of a road barrier ^.^

But y'all don't have a moveable barrier

Can't wait for nanotechnology to zip my pants after peeing

I never seen the Golden Gate Bridge in real life I wanna visit California someday when I become a long haul trucker that's probably a year from now San Francisco looks beautiful

[@bassmaster4591]

Gravecb7 Accord you're dumb the Golden Gate Bridge is in New York....

[@static_Tricolor_camry]

Bass Master That would be the Brooklyn Bridge not the Golden Gate Bridge. The Golden Gate Bridge is in San Francisco so you're either trolling or stupid

[@meepster554]

Gravecb7 Accord You may wanna visit SF in a smaller car before going in a large truck, it's very hilly. LA ans San Diego are also really pretty, they are 7-9 hours from SF driving

[@isaf60]

Gravecb7 Accord How can anyone be as ignorant as that -- not to know the location of one of the most famous bridges in the world in one of the most famous cities in the world! I know that geographical knowledge has declined in the last few decades, but this example wins the prize.

[@graziano5502]

Gravecb7 Accord lol im telling you now, you might love the view. But you are going to HATE bay area traffic

[@gunnar9767]

here in Germany we have changing digital symbols above the streets... way better

[@samuelseidel6148]

HeavyHanded that doesn't make sense, you would just have to throw up some signs, not that hard.

[@georgel9498]

In Vancouver the lions gate bridge has that

[@JaneTaylor]

The golden gate bridge has no barriers. if you watch his other video about it, it makes more sense

[@ninjabot567]

We have those here in America too. This zipper truck is better in my opinion because it puts a physical barrier between the two directions of traffic, and is much safer.

[@95TurboSol]

But it's not as cool as a giant zipper lol

[@DizzIlike]

So what do you do for a living? - I swap lanes

[@tecwzrd]

And probably makes over $100K also.

[@scottg.1776]

Micah Fischer You ain't kidding! We have the same problem here in NY and these scumbags wonder why they can't stay within local and state budgets. Also the reason behind extremely high taxes! SMH....

[@Qwertyuiop60977]

+Scott Guzman "extremely high taxes"

[@masonhales]

I'm no expert but this seems like an overly complicated way to open and close a lane

[@nero3700]

It's not simply opening and closing a lane, but swapping the direction of the center lane.

[@markperry2827]

It is rocket science for liberals

[@MeximidgeComedy]

What's a much less complicated way to just make or take a lane daily? Put cones out by hand?

[@FrozenPantiezzz]

@@MeximidgeComedy right? Is this foo stupid?

[@cr7istian956]

@@markperry2827 you’re a trumptard?

[@fritz46]

I counted at least six people inside. That's more than you need to operate a 14,000 ton bucket-wheel excavator in Germany...

[@user-os8sq3uh4n]

2:24 can't believe people think people will hit that. It's shielded by the barrier in both directions.

[@QargZer]

it can still get hit.. just chance is much smaller than the older method.
