ANTIOCH, CA – The California Department of Transportation (Caltrans) and the COntra Costa Transportation Authority (CCTA) are constructing two new connector ramps, one connecting westbound State Route 4 (SR-4) to northbound SR-160, and one connecting southbound DR-160 to eastbound SR-4. Part of this construction work entails the 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 DR-4/SR-160 connector ramp at Laurel Road. These closures are scheduled to take place on the evenings of February 25th – 27th from 11:59pm to 5:00am.
The detour for this work will be as follows:
Eastbound motorists will be directed off the highway at the SR-160 off ramp and redirected to return to eastbound SR-4 via the Laurel Rd on-ramp.
Westbound motorists will be directed off the highway at the Laurel Rd on-ramp and redirected to westbound SR-4 via the entrance of southbound SR-160.
