Construction Starts on SR 160/HWY 4 Direct Connector Ramps

State Route 160/Highway 4 Direct Connector Ramps Project is anticipated to start on Monday, March 24, 2014 in eastern Contra Costa County. The project will construct two new connector ramps, one connecting westbound Highway 4 to northbound SR 160, and one connecting southbound SR 160 to eastbound Highway 4. The ramps will create a connection between the Antioch Bridge and Highway 4 and provide residents and motorists in eastern Contra Costa County with important improvements in safety and mobility. 

Motorists are urged to use caution and slow down when entering the construction zone.

The first week in April, crews will conduct three to four days of installing cast-in-drilled-hole (CIDH) piles to support the connector ramps. (This process has been selected because it does not generate significant noise, and will minimize impacts to the surrounding communities.) Beginning in mid-April, construction hours will be extended to include two to three weeks of nighttime work to minimize daytime traffic impacts and maintain the project schedule.
