Interstate 80 will be closed in both directions from 11 p.m. Aug. 20 to 7 a.m. Aug. 21 for work on the San Pablo Dam Road interchange improvement project.
Temporary detours will be in effect (see the detour map above).
“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.”
Motorists should follow instructions posted on all on-site signage during the closure.
For more details on the closure and the project visit www.ccta.net/sanpablodamroad or call the project hotline at 510-277-0444. Construction updates will be available on Twitter at @i80spdr.
