Highway 4 Closure Sunday Morning
In preparation for the next phase of the widening of Highway 4, which will take place at Contra Loma Boulevard and G Street in Antioch, Pacific Gas and Electric Company (PG&E) is relocating some utilities.
As part of that work, PG&E will close all westbound and eastbound lanes of Highway 4, just to the west of Contra Loma Boulevard in the early morning hours of Sunday, July 17, 2011. The westbound closure will be between 1 a.m. and 5 a.m. The eastbound closure will be between 2 a.m. and 6 a.m. This work is to ensure public and crew safety while crews work to relocate high voltage power lines over the Highway.
The detours for this work will be as follows:
• Motorists traveling westbound on Highway 4 will be directed off the Highway at Lone Tree Way/A Street, right on A Street, left on W. Tenth Street, left on Auto Center Drive, and right on Highway 4 westbound on ramp.
• Motorists traveling eastbound on Highway 4 will be directed off the Highway at Somersville Road/Auto Center Drive, right on Somersville Road, continue on to Auto Center Drive, right on W. Tenth Street, right on A Street, and left on Highway 4 eastbound on-ramp.
The westbound on ramps at Lone Tree Way, G Street and Contra Loma Boulevard as well as the eastbound on ramp at Somersville Road will also be closed due to this full freeway closure. Signs will be in place at each of these ramps 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 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 Highway 4 corridor closures please visit widensr4.org.
