Overview
- CHP says a two-vehicle collision in Bore 2 on Thursday triggered a vehicle fire and an eastbound shutdown.
- After crews reached the scene, the right eastbound bore (Bore 3) reopened, but Bore 2 remains closed.
- Westbound traffic continues through both bores as officials manage the response in the affected tube.
- CHP has not given an estimated time to reopen and urged drivers to use alternate routes.
- The Caldecott Tunnel on Highway 24 links Oakland and Contra Costa County, so even a partial closure can quickly snarl East Bay commutes.
