- 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:

I can sleep better tonight after years and years of wondering how the hell those things moved!
Merchant Ivory same lol
Merchant Ivory hahaha😂😂😂😂
Who else wanted to see that thing go 100 mph moving the barriers 😂
keeblerelmcookies That would be epic.
Lol same
🤣😂😅😵🤔🌹
Probably sound like cracking a whip!
I never knew of the existence of such a machine/vehicle until I came across this video in my feed.
my sentiments exactly
If that thing breaks do people then yell out the window as they drive by "hey, your zipper is down!"?
😁
That's not funny. It's embarrassing
you got me there>.
I'm going to need this zipper for my old Levis.
I live in San Francisco and honestly my dad says it isn't even a traffic hazard, we've never had and bad experiences.
Morty Sanchez
Someone put in pocket hundreds of thousands of dollars.
In case that piece of equipment breaks down.
Does the boss tell the highway worker,
"Your zipper is down"?
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.
128 head-on collisions with 16 deaths in 40 years in less than one mile is statistically significant. So much so that traffic engineers and planners decided to install a movable median barrier.
I lived in San Francisco from 1973 until 1980. Guess what? The traffic ran better than it does now and the number of accidents has gone up, not down, because of stupid, idiotic drivers.
@@captainklar4923 are you sure the amount of traffic hasn't increased?
1:40 Hopefully the driver will be a big brave boy and try it without the stabilizers next time! We'll all rooting for you Timmy!
O L hahahaha
Well that's 1 way to do your 8 hour work day just roll back and forth the whole day LMAO
I drive across The Golden Gate Bridge on a weekly basis and this moving wall is something to behold. This safety wall has been needed for years.
This shit is like 2 years old and the comments are fresh
Clorox Bleach right lmao
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.
Yep agreed, but solution was adopted rather than created.
This is one of the strangest comment sections I've ever seen. Its just pure unfiltered chaos
Yeah immediately after I saw this comment I scrolled down and saw a comment on how gay san francisco is and how theres a quote "disco ball in there with 5 men getting it on" 😂
We can always get you some filtered chaos. And would you like fries with that?
@@simpleman8883 Most if not all of the gay clubs in SF are in a small neighborhood known as the Castro. Maybe you will find your gay disco ball there. The rest of the city actually is pretty comparable to other large cities as far as gay rights and gay businesses are concerned.
@@mharris5047 Ok, thanks for the trivia, though I never implied malice in my coment, just that there was a comment I found funny.
The God's of TH-cam decided that today this video should be go viral.
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.
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.
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)
It changes to 3 lanes from 2. Going into S.F. and then going out at evening rush hour. Pretty cool
In Germany, we have electronic signs that indicate the lanes you can use on your side, but this looks cooler
Poggy LP Americans are to stupid for that. there would be so many head on collisions.
Sean Gillis We have some in Seattle
Sure we do, on the Highway, where the lanes already are seperated.
You wont find a single road that is seperated only by signs, you need a barrier. Or an alternative marking in the colour yellow, in case of a smaller road.. ;)
ToysOmadnesS so you have never been to Berlin I guess?
I´ve lived there for a year. Where the hell should that be?
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.
Amazing. Thankyou for explaining
I've never seen any turns on the bridge...a streaker in the early 70s...I grew up w the 🌉🌉... 💕 seeing comments...I remember the guy in on the truck w the cones...I saw him doing it at times 🌉💖🌹.if and when it gets destroyed..part of my life will fade...let's hope it stays around 🌉💖
Can a Brit just say that this idea is utterly brilliant. Way to go Guys.

I'm glad u said what it is in what it does...lol I honestly thought it was a ride or tourist thing so u can look out better than u wud in a car
where is this from ?
Has this video been on everyone's recommended? So many comments from today.
2:52 Hold up is that fucking BMW Missing a Full Headlight?
Yes
Don't worry about it. they never work anyway. Just like the blinkers, speedometer and mirrors. :P
This comment section is actually the greatest piece of entertainment ive ever witnessed
I agree. This is like the B-Ark from Hitchhikers Guide to the Galaxy.
Looks like they switched it to favor the side that will be getting the most traffic. It cost about a billion to create another golden gate bridge. Editing this one to add more lanes would be pretty costly I assume. Spending a few million dollars on this is pretty smart.
the rush hour will be over before this thing reached the other side....
How did I live all this time and not know about this!!!! Wow!
The tiny wheel in the back is like a lifeguard at the Olympics.
Never even knew something like that existed but it makes sense now
That is awesome! I could not do that job for long though. It protects the workers, and helps with traffic. Super cool!
Helps with traffic depending on the direction and time of day. Smart.
why are there so many idiot comments. The machine allows for higher traffic volumes during peak hours in either direction. when people are heading to work the machine makes that direction have an extra lane and vice versa when people are heading home.
@Suchan Kim probably two shifts.
@Suchan Kim They probably only run that machine twice a day. It's not running 24/7.
In Australia, we just have lights overhead that show green and red during peak and off peak. This seems likes overengineering a simple problem.
i think this huge truck sitting in the middle of the road (moving the barriers to decrease traffic in the busiest lane), is actually increasing traffic in both lanes more than decreasing. It seems to have a reverse effect to the desired one... Cars even have to slow down when passing near the truck, hence putting pressure in the traffic, then they also have an entire lane closed because of that truck... It just seems pretty stupd...
@@namewasstolenstresslevel2111 the truck is not running all the time. It moves the wall and gets out of the way.
heavy vehicle used to transfer concrete lane dividers, such as jersey barriers, which are used to relieve traffic congestion during rush hours. Many other cities use them temporarily during construction work
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.
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.
The Golden Gate Bridge is also a significant distance from city centres (3kms in one direction and 6kms in the other) as opposed to the Harbour Bridge which is smack bang in the middle of heavily populated urban areas, making access far easier.
Apples Oranges
@@ondrejsedlak4935 wouldnt width be more relevant mate. I noticed u didnt mention that.
You dont need emergency vehicles when u dont drive like fuck wits in peak hour.
@@ondrejsedlak4935 You said "have room to pull over safely" thats a width issue not a length issue. The time it takes to set up 3k of road is time wasted in peak hour where you can instantly flick a switch, save on wages, remove a massive obstruction that blocks two lanes while being set up and even make one an emergancy lane that can be triggered by the same lights if there is an incident..
@@hiz24airness In an ideal world…
in morning hours cars drive more from outside city to inside city limits and viceversa in the evening so this helps it. and where road can't be widened.

How does the TH-cam recommendation process work?
If you're getting random videos recommended to you, then obviously random!!
@@raecarta118 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
Horribly
I can honestly say, I didn't search zipper also.
If a lot of people watch a video at the same time then the algorithm recommends that video to other people, it's YT trying to get users (especially new users) occupied watching more and more videos
got one of these here in Boston; opens HOV for inbound traffic in the morning, southbound in the afternoon
seths1997 thats pretty smart to use it that way then the traffic going to work in the morning has an extra lane and going home in the evening has an extra lane
While in Melbourne we simply got a digital sign telling when the lane is open for inbound or outbound traffic.
seths1997 I just remember a couple years ago that a deer jumped into the open side door of it
Kni same thing in Vancouver last time I was there too lol
Very cool, I never saw a thing like this before.
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. It's likely not very expensive in the end, or breaks even, or makes money. Also, it needs a barrier, there are a lot of cars and most of the time going 50+mph, it's basically a freeway.
Fr the conservatives just tryna find anything to shit on 😂. They lack such common sence
I used to be the BEST road zipper in the world 'till this darn machine done took ma jerb!!!
"...Zipper in action at the tail end". Just another day in San Francisco.
spookym123 Ooh, cheeky!
Unusual, as never seen one of those before. Cheers for posting anyway.
I like it. The Golden Gate's lanes are narrow, and without the barrier it's nerve wracking. They were probably tired of horrible accidents on the bridge. So this was a good idea.
When you try to zip your pants back but you're drunk as fuck
Thanks TH-cam recommendations
I completely understand the concept of the machinery.
But why in the flying yellow fuck was he going back & forth.
Techxxz ...caltrans hourly employee.
Techxxz the hours won't milk themselves
ever zip pass the franks and beans? gotta back it up
Such a very big improvement on the old system. There were usually three accidents a day under the old system.
I can think of about 25 roads around metro Atlanta that needs this.
I wonder what other type of vehicle machines exist in the world that we don't even know about.
very first time i ever seen one thnks for sharing
Man, I love seeing this stuff, and I also love when people get into fights about it because I just get to laugh at them as I live on the other side of the U.S.
Things you don't miss when you move to the country! 😉

That would be a boring ass life being alone in the fuckin country
I love all the self-proclaimed civil engineers on here.
never, never toss around any kind of expert title with the word engineer in it...they complicate everything according to their specialty....common sense and a bit of elbow grease will out think an engineer every time...
it's not just civil engineers lol. mechanical engineers, electrical engineers, ... That specialized truck is honestly pretty ingenious.
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.
Two years later and I'm fascinated about this 😳😤😂
We have the same concept in Denver as HOV lanes. They are a dedicated, separated, 2 lanes in the center of the highway with gates to allow traffic for rush hour in either direction as necessary. A bit safer and less costly in the long run.
That is a cool machine!
In England, two men in a truck, one driving, the other chucking cones out, 1 mile covered in about10 minutes, simples !
and how does that prevent loss of life in the inevitable accidental head on collision? it doesn't. The GG bridge used to use cones, and people died because people are generally crappy drivers.
you really want people driving face to face at 45 miles each with only a plastic cone between the two of you?
Mark Weinhardt
Obviously not, that’s why we only use them to close off lanes or create contra flows, on each respective side of the carriageway, they are never used in the UK, to divide a lane between oncoming vehicles, which would be suicidal.
Which is why this was such an incredible deployment. Head on collisions on the GGB were horrible...
I counted 6 operators in the dual cabs, and two dudes on the ground. Seriously? There is no way that is necessary!
Maybe they were training or something.
They are def training. You can tell by what they are doing.
They use this same system in San Juan Puerto Rico. It did a good job reducing gridlock, back when they had a lot of people there.
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'.

Ouch
Go work for GE in the medical department.
In Germany we have lights at the street that show you which direction you gotta drive...so this looks kind of weird xD
Yeah, but for that you either need to shut down the entire lane until it's cleared so you can switch, or you need redundant lights/tracking systems to know which part of the lane is cleared to reverse it piecemail. I think this is a better solution. More analog, less room for human error.
If being alive has taught me anything, it's that making it harder for humans to screw up is in everyone's best interests.
Anyone else find this satisfying?
you must be fun at parties, it's a joke lol
at 2:51 the BMW has a missing headlight :p
Intense stuff right here
Jack Mehoff diabetes
diabeetus!
In addition, this of you who can can understand why they just don't add lanes...OMG. The cost, the upheaval, the sheer magnitude of widening this iconic bridge built in 4 years in mid-1930's. It's a national landmark, not just a random bridge.
looks like it would take all damn day

only machinery
I assume the 1.7k people that dislike this have to drive with this thing on the road everyday
iwant crawfish only time it's on the road is when it's moving the barriers.
They've got a budget for 2018 to buy a Velcro lane divider instead.
Neighbors oppose the idea based on the sound.
If you crash your car into it, would this be described as getting "caught in the zip"?
AerialExplorer No
That's fantastic!!!! Great share
Thanks for posting! That is a very cool solution.
+Mike Spille You are quite welcome!
This is a most interesting machine! Looks like it could save a life or two
hammer slamper what are you talking about
Chuck King no bodies moving cones!
Why isn't there an app for your cellphone so you can just download extra lanes?
The guys in New Zealand have got this perfected... the lane changes are done in minutes with no disruptions. Peak hour morning traffic gets extra lanes into Aukland and less leaving the city. In the afternoon the process is reversed... like clockwork...
That's a great concept.
great post, big like, from Germany

Ahaha thanks for the info
Bigger Brudda Gee, thanks captain obvious, i would never have fucking guessed. But this comment is not good enough. I hate TH-cam. We must build a wall. The wall is gonna be huge and i gonna let TH-cam pay for it.
Great work there! Oh and a nice day to everybody reading this! :)
A masterpiece in engineering
Very slow and look how many people the thing takes to operate. Should be a one man job with a machine that size.
Pretty nifty thing you got there.
This is the safest way to micro manage traffic congestion at certain periods of the day ie peak hour periods morning and night traffic crossing the bridge to and fro from the city. They have a similar type of BTM in Auckland New Zealand on the Harbour Bridge actually 2 one follows the other moving while opening or closing 2 lanes at time
That thing is pretty cool to watch.
I never knew such a thing existed. Amazing!

Cool. I didnt realize the bay area had this. Hawaii (Oahu) has had a zipper lane for morning commute traffic from the west side of the island since 1998.
Fascinating!
I was expecting it to work like a zip, splitting the bridge in 2. That would've been worth watching
