The Contra Costa Transportation Authority (CCTA), the California Department of Transportation (Caltrans), the Metropolitan Transportation Commission, and the City of San Pablo broke ground on an interchange improvement project on Interstate 80 at San Pablo Dam Road earlier this year.
To facilitate the next phase of work, we must temporarily close a section of the freeway in order to help ensure public and motorist safety.
What to Expect:
- Interstate 80 will be temporarily closed in the eastbound and westbound directions between San Pablo Avenue and San Pablo Dam Road
- The closure will occur from Saturday, August 20th at 11:00 p.m. until 7:00 a.m. Sunday, August 21st
- Temporary detours will be in effect (please see the detour maps below and on pages two and three of the attached document)
- Motorists should follow the instructions posted on all on-site signage
Now that the roadway deck has been poured for a new pedestrian overcrossing at Riverside Avenue, which will replace the current overcrossing, these closures will enable crews to remove the falsework (support structures) that were previously constructed. When complete later this year, the new overcrossing will extend across Amador Street, enhancing safety for Riverside Elementary School students and the community.
