The California Department of Transportation (Caltrans) and the Contra Costa Transportation Authority (CCTA) are widening State Route 4 (SR-4) through Pittsburg and Antioch. As part of this construction work, the contractor for the Somersville Road project will close all lanes on westbound SR-4 between Loveridge and Somersville Roads for several hours on Thursday evening, March 29, 10:00 pm to 3:30 a.m.
In addition, eastbound SR-4 will be closed between Loveridge Road and Somersville Road Thursday evening, March 29 from 11:59 p.m. to 5:00 a.m.
The westbound 0n-ramp and both eastbound on-ramps will be closed at Loveridge Road during these freeway closures.
Detour signs will be in place to direct motorists to alternate routes. Please be alert and carefully follow all directional signs when encountering detours.
Motorists are advised to expect delays and allow extra time for their commute. Please drive with caution through the detour and leave a safe traveling distance between your vehicle and the vehicle ahead of you.
