Overnight I‑80 Closure Near Carquinez Bridge

Caltrans will shut the Crockett/Pomona Street off-ramp and one eastbound Interstate 80 lane near the Carquinez Bridge for two overnight work windows next week, the agency said in a May 14 notice. The closures are scheduled for Tuesday, May 19, 2026, and Wednesday, May 20, 2026, from 9 p.m. to 5 a.m. the following morning, according to Caltrans District 4. The work is tied to reconstruction of a damaged crash cushion at Exit 27 in Crockett, which Caltrans described as the last eastbound exit before the Carquinez Bridge toll plaza. The agency told motorists to expect delays, use posted detours and check live traffic conditions before leaving. ### Which stretch of I-80 is closing, and when? Caltrans said the affected area is eastbound I-80 at the Crockett/Pomona Street off-ramp in Contra Costa County. The closure window is 9 p.m. to 5 a.m. on the nights of May 19 and May 20, the agency said. Lane 3 on eastbound I-80 will also close from east of the Cummings Skyway on-ramp to the Pomona Street exit, according to the Caltrans notice. Drivers approaching the work zone will have to merge before reaching the exit area. ### Why is Caltrans doing the work now? The May 14 Caltrans notice said the overnight closures are needed “to continue to facilitate reconstruction of a damaged crash cushion.” The agency did not say in that notice when the crash cushion was damaged or how long the repair itself will take beyond the two scheduled nights. April and May have already brought a series of overnight closures on eastbound I-80 between McDonald Avenue and the Carquinez Bridge for Caltrans fiber-optic work, according to separate District 4 construction updates. Caltrans said those lane and ramp closures were scheduled during overnight hours to reduce traffic disruption. ### If I need the Pomona Street exit, where do I go instead? Caltrans said motorists who want to reach Pomona Street in Crockett should take the eastbound I-80 Cummings Skyway off-ramp and then use San Pablo Avenue or Crockett Boulevard to reach Pomona Street. The agency said changeable message signs will be posted to alert drivers to the closure. (dot.ca.gov) Westbound State Route 4 traffic is also affected by the detour pattern. Caltrans said drivers traveling westbound on Highway 4 and trying to reach Pomona Street should take the Cummings Skyway off-ramp, then continue on Crockett Boulevard to Pomona Street. ### Will this be the only overnight roadwork in the corridor? (dot.ca.gov) Caltrans said separate fiber-optic construction has been producing nightly lane and ramp closures along eastbound I-80 between McDonald Avenue and the Carquinez Bridge throughout May 2026. Those closures have generally been scheduled Sunday through Thursday from 9 p.m. to 5 a.m., according to the agency’s April 6 update. (dot.ca.gov) The agency said closure schedules are subject to change or extension, and the state lane-closure reporting site says all closure information is continually updated. That means drivers could encounter overlapping work activity elsewhere on the corridor even if the Pomona Street repair is the immediate issue in Crockett. (dot.ca.gov) ### Where should drivers check before heading out? Caltrans said motorists can use QuickMap for real-time traffic and the District 4 lane-closure information page for current closure listings. The agency also said drivers should reduce speed near work zones, allow extra travel time and be prepared for merging traffic. (dot.ca.gov) May 19 at 9 p.m. is the next scheduled start time for the Crockett/Pomona Street closure, according to the Caltrans notice, with a second overnight closure set for May 20. Caltrans said all work is weather dependent and subject to change. (dot.ca.gov)
