A safer Golden Gate Bridgewith The Road Zipper System.

How a moveable barrier transformed safety and mobility on one of America’s most iconic structures bridging safety and flexibility in the heart of San Francisco.

When the Golden Gate Bridge first opened in 1937, it was hailed as an engineering marvel. But by the 21st century, its center lanes—shared by opposing traffic—had become a safety risk. With only plastic pylons separating northbound and southbound vehicles, the bridge faced a growing threat of head-on collisions, particularly during high-speed peak travel.

Faced with rising traffic volumes and limited space for physical expansion, bridge engineers needed a smarter solution—one that could adapt to traffic patterns, improve safety, and preserve the historic structure’s integrity. That’s where The Road Zipper System™ came in.
