Overnight Highway 4 Closure (Antioch): February 25-27, 2015
The California Department of Transportation and the Contra Costa Transportation Authority are constructing two new connector ramps, one connecting westbound State Route 4 (SR-4) to northbound SR-160, and one connecting southbound State Route 160 (SR-160) to eastbound SR-4 in Contra Costa County.
Part of this construction work entails adjustment of temporary bridge supports that span over SR-4. In order to ensure crew and public safety during this work, the contractor will close all lanes of SR-4 in the eastbound and westbound directions between the SR-4/SR-160 connector ramp and Laurel Road.
These closures are scheduled to take place on the evenings of February 25, 26, and 27th from 11:59pm to 5:00 am.
The detour for this work will be as follows:
- Eastbound motorist will be directed off the highway at the SR-160 off-ramp and redirected to return to eastbound SR-4 via the Laurel Road on-ramp.
- Westbound motorist will be directed off the highway at Laurel Road on-ramp and redirected to westbound SR-4 via the entrance of southbound SR-160.
Motorists are advised to expect delays and allow extra time for their commute. Please drive with caution through the detours and leave safe traveling distance between your vehicle and the vehicle ahead of you.
