May 19, 2020 El Sobrante, CA – The Contra Costa County Public Works Department will begin construction of the San Pablo Dam Road Traffic Safety Improvements project between the city limits of Richmond and city limits of Orinda. Construction will start Wednesday, May 27, 2020 through July 31, 2020, 8:00 am-4:00 pm, Monday-Friday, barring unforeseen circumstances. Drivers can expect traffic delays up to 30 minutes.
The project will consist of installing a centerline rumble strip and channelizers, reconstructing median islands, replacing roadside signs to meet new retro-reflectivity standards, installation of speed feedback signs, partial slurry seal, removal and replacement of thermoplastic stripes and pavement markings, and re-striping of a bike lane at two intersections of San Pablo Dam Road and Old San Pablo Dam Road. Current shelter-in-place and social distancing protocol will be followed.
