Construction on Bailey Road/State Route 4 Interchange

Contra Costa County Public Works to Begin Construction on the

Bailey Road/State Route 4 Interchange Pedestrian & Bicycle Improvement Project

 

March 24, 2021, Bay Point, CA – The Contra Costa County Public Works Department will begin construction on the Bailey Road/State Route 4 (SR4) Interchange Pedestrian and Bicycle Improvement Project on Monday, March 29, 2021 through October 2021, barring unforeseen circumstances. Work will occur Monday through Friday, between 7 a.m. and 4 p.m., weather permitting. Construction will be scheduled to minimize impacts to commute traffic. Drivers should expect delays and detours during construction. Current social distancing protocol will be observed. 

 

The work will consist of removing the SR4 westbound loop off-ramp and pedestrian tunnel, as well as squaring-up the intersections of SR4 eastbound on and off-ramps, and removing the free right turns. Work also includes widening the SR4 westbound diagonal off-ramp, installing a traffic signal for traffic to go north and south bound on Bailey Road, modifying existing traffic signals, installing storm drain modifications, installing sidewalk along Bailey Road, and overlaying the pavement on Bailey Road within the interchange area. 

 

Funding for this project is provided by a federal Active Transportation Program grant and local road funds made up of gas tax revenues provided by the SB1 Road Repair and Accountability Act, Navy Mitigation funds and Keller Canyon Mitigation Funds. More information for this project can be found at http://www.cccounty.us/pwdmap.
