July 2017 – Balfour Road Update


The Contra Costa Transportation Authority (CCTA) is beginning construction of the new Balfour Road Interchange at Highway 4. The Balfour Road and Highway 4 intersection is currently signalized, resulting in traffic backups during peak commute times. This project will replace the at-grade intersection with a new interchange at this location.

This is the final phase of bypass construction to improve traffic flow on Highway 4. The bypass projects on Highway 4 were developed cooperatively among the Contra Costa Transportation Authority, and the cities of Brentwood, Antioch, and Oakley to ease traffic congestion along Highway 4. To view a video rendering of the interchange, please watch below.

Construction Work

Daytime construction work is starting soon on July 17th! Construction work on Balfour Road with potential lane closures will occur either on weekdays between 5 am and 5 pm or on weeknights between 8 pm and 5 am. Please see below for construction hours on both Balfour Road and Highway 4. One lane in each direction will remain open at all times on Balfour Road.

Construction signs are in place along Highway 4 and Balfour Road. Please anticipate delays during your regular commute.
