Highway 4 Full Freeway Closure in Pittsburg and Antioch
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 will begin demolishing the abandoned roadway bridge and railroad bridge over the highway at Loveridge Road. In order to ensure crew and public safety during this work, the contractor will be doing complete closures of SR-4 in both directions overnight during the next several weeks. The closures will take place on Monday nights through Saturday mornings for approximately 4 weeks beginning on June 18, and continuing until approximately July 13, 2012. The eastbound closure will take place between 12:30 a.m. and 5:30 a.m. The westbound closure will take place between 10:00 p.m. and 3:30 a.m.
The detours for this work will be as follows:
o Eastbound motorists will be directed off the highway at Loveridge Road and immediately back on the highway at the eastbound SR-4 on-ramp from Loveridge Road.
o Westbound motorists will be directed off the highway at Somersville Road/Auto Center Drive exit, left on Somersville Road, continue on to Auto Center Drive, left on Tenth Street, left on Loveridge Road, right on California Avenue, and left on westbound SR-4 on-ramp.
Motorists are advised to expect delays and allow extra time for their commute. Please drive with caution through the detours and leave a safe traveling distance between your vehicle and the vehicle ahead of you. Caltrans and CCTA appreciate your patience as we work to improve the highways. For the most current information on all SR-4 corridor closures please visit our web site at: http://widensr4.org.
