Highway 4 G Street Ramps to Close Permanently March 12

Major Milestone Reached on Highway 4 Widening Project

CONTRA COSTA COUNTY – The California Department of Transportation (Caltrans) and the Contra Costa Transportation Authority (CCTA) are widening State Route 4 (SR-4) through Pittsburg and Antioch. A major part of this project involves the reconfiguration of the G Street interchange to remove the on-ramp and off-ramp at G Street and to construct a new wider G Street bridge for local traffic.

On March 12, the project will reach a major milestone with the permanent closure of the highway ramps at G Street. The westbound ramp will close at 11:00 pm on Monday, March 12. The eastbound ramp will close at 11:00 pm on Tuesday, March 13. Prior to closing the eastbound off-ramp, operational improvements will be made to the eastbound off-ramp at Contra Loma Boulevard.

The reconfiguration of G Street will be combined with a full service interchange at Contra Loma planned for project completion in spring 2015. Together, these changes will provide better access to the highway and improve local traffic circulation.

Caltrans and the Contra Costa Transportation Authority have been working with the City of Antioch and the Antioch Unified School District to notify residents of this construction and provide safe routes to school.

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. 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.

    Frankly, this sucks! We bought our home on Putnam Street back in 1987 because of the convenience of the G Street on & off ramps to Hwy 4.
