A safer Golden Gate Bridge with Road Zipper.
In early 2015, the Road Zipper System was installed on San Francisco's iconic Golden Gate Bridge. Since then, one of the world's most photographed—and busiest—bridges has been moving traffic faster and more safely than ever before.
Behind the picture-perfect installation.
Lindsay partnered with the Golden Gate Bridge, Highway & Transportation District to engineer a streamlined and custom-made version of the Road Zipper System to fit the Golden Gate Bridge’s narrow lanes. While previously the bridge carried three lanes of traffic in either direction, the new system allowed the bridge to retain six lanes but easily be reconfigured to feature up to four lanes in one direction and two in the other. This flexibility is helping the Golden Gate Bridge better cope with daily commuter traffic needs—now and in the future.
Discover the advantages of future flexibility.
- The Golden Gate Bridge currently carries around 110,000 vehicles/day on Highway 101, with that volume projected to rise to 138,000 vehicles/day by 2038
- 11,500 feet of barrier consists of 12-inch wide x 32-inch high steel-clad units filled with high-density concrete
- In one pass, the moveable barrier is transferred 11 feet and gently set down without damaging the road at speeds up to 10 mph
- Our barriers can withstand the force of a 4,400-pound truck traveling at 62 mph, virtually eliminating crossover collisions
