To reduce congestion on eastbound Interstate 580, MTC and its partners are working to convert the right shoulder to a third freeway lane from the Sir Francis Drake Blvd. on-ramp in Marin County to the Richmond Parkway/Point Richmond exit in Contra Costa County. Project elements include reconfiguring the Main Street on-ramp from San Quentin Village with a retaining wall to improve the traffic merge with the new lane; replacing pavement on the bridge approaches to accommodate heavier traffic loads; and relocating a retaining wall in Richmond to achieve safe sight distances for vehicles traveling in the new right lane. The third eastbound traffic lane is scheduled to open in the fall of 2017.
To provide a bicycle/pedestrian link between Marin and Contra Costa counties, the agencies will establish a path on the north side of Interstate 580, with concrete barriers to separate bikes and pedestrians from westbound freeway traffic. These include a moveable barrier on the upper deck of the bridge that will allow Caltrans to conduct maintenance work during short closures of the path. Construction work on the moveable barrier project is expected to begin in the spring of 2017, with completion slated for the spring of 2018.
Lane & Ramp Closures
Lane and ramp closures necessary for construction activity will take place mostly in late night and early morning hours, but some closures may extend until 8 a.m. on Saturday and Sunday mornings.
Each Open House will be an informational meeting at which members of the public can review project plans, talk with project team members and provide input.
