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:
