VALLEJO — Caltrans maintenance crews will close two eastbound lanes on the I‑80 Carquinez Bridge starting early Sunday, Sept. 27, in a move that will affect travel between Vallejo and points east. The closure will run on the bridge approach from the Cummings Skyway overpass to the Carquinez Toll Plaza, beginning at 5 a.m., the agency announced Friday.
Why crews are closing lanes
The temporary lane shutdown is being used to address and repair lighting issues on the bridge approach from the Pomona on‑ramp. Caltrans said the repairs aim to improve conditions for drivers and for the workers conducting the maintenance.
“Addressing these issues will make it safer for motorists and crews.”
The work comes about a month after crews closed the bridge in the westbound direction to repave the entire westbound bridge deck. In recent weeks, Caltrans maintenance teams have also carried out a package of routine upkeep on the Vallejo side — from the foot of the bridge to Highway 780 — that included vegetation control, litter and graffiti cleanup and other tasks intended to prolong the facility’s service life.
What to expect for travel
Motorists who use I‑80 to and from Vallejo should expect altered lane patterns through the closure zone and possible slowdowns during the work window. The closure affects a key stretch of the interstate where traffic funnels across the Carquinez Strait, and any restrictions can ripple into local streets as drivers seek alternate routes.
- When: Starting Sunday morning, Sept. 27, at 5 a.m.
- Where: Eastbound I‑80 from the Cummings Skyway overpass to the Carquinez Toll Plaza (approach from Pomona on‑ramp)
- Purpose: Repair lighting issues on the bridge approach and improve safety for drivers and crews

Context: a string of bridge and corridor projects
The Carquinez Bridge work is the latest in a series of maintenance and improvement actions on this stretch of I‑80. Caltrans completed a full westbound deck repaving roughly a month earlier and has been performing maintenance through Vallejo between the base of the bridge and Highway 780. Agency officials framed those efforts as part of a project to provide a smoother, safer driving surface while extending the service life of this critical regional connection.
For Vallejo, a city that relies on I‑80 for commuter traffic, goods movement and regional access, periodic maintenance is necessary to keep the corridor functioning but also presents short‑term disruptions. Drivers should plan extra travel time for trips that cross the bridge, consider alternate commute windows where possible, and monitor Caltrans traffic advisories for updates on lane change timing and any extensions to the work schedule.
Local transit providers and freight operators that rely on the I‑80 link may also adjust schedules in response to the closure. Caltrans has said the lighting work is intended to improve safety for both motorists and the maintenance crews doing the repairs, a common rationale for lane restrictions on busy, constrained bridge approaches.
Vallejo residents can expect additional service and repair activity in the corridor as Caltrans continues its maintenance program; those actions include vegetation control, litter and graffiti removal and other routine tasks that accompany larger pavement and structural work on the bridge.
Caltrans will post further information as available. Motorists should follow posted signs and speed restrictions and watch for workers in the closure zone.
