Crews will begin work this week to install a moveable concrete barrier (similar to the barrier on the Golden Gate Bridge) that will separate the two westbound traffic lanes on the upper deck of the Richmond-San Rafael Bridge from a new bicycle/pedestrian path that is expected to open later this fall. Installation work began earlier this week, and will take place in the overnight hours of 9 p.m. to 5 a.m. This work will restrict westbound traffic across the bridge to the far left lane each weeknight through October. The four-mile-long bridge path will connect to another new bicycle/pedestrian path that runs along the north side of Interstate 580 in Richmond and is protected from freeway traffic by a permanent concrete barrier. Together, these bi-directional paths stretch for almost six miles from Castro Street in Richmond to East Francisco Blvd. in San Rafael, providing the first route for bicyclists and pedestrians traveling between Marin County and the East Bay. These new paths are a link in the planned 500-mile Bay Trail network. To learn more about this project, visit the Metropolitan Transportation Commission’s website or call them at (415) 778-6700.
