Caltrans will close westbound Interstate 580 on the Richmond-San Rafael Bridge from 11 p.m. Saturday, Nov. 14, until 8 a.m. Sunday, Nov. 15, to install a gantry for open-road tolling, the agency said.
Access to Stenmark Drive will remain open for residents. The bike and pedestrian path will close from 9 p.m. Saturday to 8 a.m. Sunday. The Chronicle reported that eastbound lanes on the lower deck will stay open, and that crews plan to hoist a preassembled steel gantry into place overnight. Caltrans spokesperson Matt O'Donnell told the paper rain would not stop the crane work, but strong wind could force a delay.
The Richmond-San Rafael Bridge is the first of the Bay Area's seven state-owned toll bridges to start the conversion to all-electronic, open-road tolling. Caltrans said toll booths are scheduled to be reconfigured in December 2026 and removed in winter or spring 2027, with the project targeted for completion in summer 2027.
