  • Traffic Advisory for the Closure of the Southbound State Route 160/State Route 4 Connector Ramp on July 31, 2016

    STATE ROUTE 160 FULL FREEWAY CLOSURE IN THE ANTIOCH AREA

     

    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. As part of this construction work, the contractor will be closing a segment of State Route 160 (SR-160) to install new traffic delineation interfacing with the newly completed westbound SR-4 lanes. In order to ensure crew and public safety during this work, the contractor will close all lanes of SR-160 in the southbound direction between Main Street / E. 18th Street and the SR-4 / SR-160 connector ramp. This closure will occur on the evening of July 31st from 10:00 pm to 4:00 am.

    The detour for this work will be as follows:

      • Southbound motorists will be directed off the highway at Main Street/ E. 18th Street proceeding west on E. 18th Street to Hillcrest Avenue. Motorist will then be directed to proceed south on Hillcrest Avenue to the SR-4 westbound on ramp, please see attached.

    WB 160 Connector Ramp Closure

    The SR‑4 Widening Project includes over $540 million in State, Federal, and Contra Costa Measure J sales tax, and other local funds to widen SR‑4 from four to eight lanes between Loveridge Road and SR‑160. The combined effort of Caltrans and the Contra Costa Transportation Authority on projects in the SR-4 corridor will reduce congestion, create a safer roadway, improve operations, and reduce traffic delays on this important east‑west connector.   When completed, the SR‑4 highway median will be used to extend BART service from Pittsburg/Bay Point to a new Antioch station at Hillcrest Avenue.

    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.
