[ARCHIVED] Byron Highway Traffic Safety Improvements Project

Contra Costa County Public Works to Begin Construction on the Byron Highway Traffic Safety Improvements Project

May 31, 2019, Byron, CA – Contra Costa County Public Works will begin construction on the Byron Highway Traffic Safety Improvements Project. The project consists of an asphalt overlay on Byron Highway between Byron Hot Springs Road and the Alameda County line, restriping the centerline to feature double yellow no-passing lines and a centerline rumble strip, and replacing striping and pavement markings. Additionally, all signs along Byron Highway will be replaced to meet new reflectivity standards. The total project length is approximately 3.8 miles.

Construction will begin on Wednesday, June 5, 2019, with completion in late July 2019, barring unforeseen circumstances. Work hours will generally be in the evening from 7:00 pm to 6:00 am to minimize impacts to commute traffic. Drivers can expect delays of up to 15 minutes during construction.

Funding for this project is provided by the Highway Safety Improvement Program, and gas tax revenues provided by the SB1 Road Repair and Accountability Act. More information for this project can be found at
