The Bay Area Toll Authority (BATA) has begun construction on the Richmond-San Rafael Bridge Access Improvement Project to ease traffic congestion, improve vehicle access to the bridge, and establish a bicycle/pedestrian path connecting Contra Costa and Marin counties.
This exciting project will employ an innovative approach for congestion relief by converting the existing eastbound shoulder to a third lane during evening commute hours. Electronic signs will be used to indicate when the third lane is open to eastbound motorists. After the third lane is completed (weather-permitting in late 2017), a bicycle/pedestrian path will be built on the upper deck to connect critical portions of the San Francisco Bay Trail.
Beginning this week, travelers will see the installation of temporary striping and barriers (k-rail) to protect construction workers along eastbound 580.
- Shoulder Closures –The right shoulder of the eastbound Richmond San Rafael Bridge will be closed from 5am to 2pm daily during the week of Jan. 23. Both traffic lanes will remain open.
- Nighttime Construction– Through Saturday morning, Jan. 28, temporary striping and barriers (k-rail) will be installed along both eastbound and westbound I-580 from Sir Francis Drake Blvd. in Marin County to Castro Street in Contra Costa County. One lane will remain open at all times
- Bicycle Shuttle By Request – Starting Thursday January 26, the existing bicycle access on 580 between Marine Street and Stenmark Drive in Richmond will no longer be available. In lieu of freeway access, a free shuttle with bike racks will be available from 7am to 7pm. PLEASE NOTE: The shuttle may take up to 20 minutes to arrive once called (510-715-1465). Cyclists will no longer have access to freeway shoulders.
During the week of Jan. 30:
- Main Street Eastbound On / Off Ramp Closures – Temporary nighttime closures of the eastbound I-580 Main Street on- and off-ramps in San Rafael will occur. The San Quentin/Main Street off-ramp will be closed from 7pm to 6am; and the on-ramp will be closed from 9pm to 6am. Please see detour maps below.
February Nighttime Construction
- Starting in February, the contractor will relocate a water main under Main Street between Francisco Blvd. and the eastbound I-580 on- and off-ramps. Construction will occur at night to minimize traffic impacts.
Notice: This information is based on the work plans submitted by the contractors which are subject to change for various reasons. For the most current information on all lane and ramp closures please check the web site shown below before beginning your travel.
