Balfour Road

Project Description

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.

Project Milestone Achieved

The Balfour Road Interchange project passed another milestone last week when concrete was poured for a new bridge deck that will be one of the new on-ramps for the future interchange.  Check out some amazing images and a 30-second timelapse showing the construction team finishing the concrete.
