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 in October 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.

Construction crews also recently completed another project milestone in December by installing the girders, which are precast concrete support beam bridges, for the Deer Creek Bridge. This is the next step in the completion of Deer Creek Bridge on the Balfour Interchange.
