State Route 4 Balfour Road Interchange (Phase 1)

East County
PROJECT BUDGET $73.6 Million
PROJECT SPONSOR
CCTA & SR4 Bypass Authority
LOCATION:
SR 4 at Balfour Road in Brentwood.
STATUS:
Under Construction

The SR 4 Bypass project was developed cooperatively among Contra Costa County and Antioch, Brentwood and Oakley to ease traffic congestion. In February 2012 Caltrans adopted the Bypass as its new State Route 4, replacing the segment of State Route 4 that passes through the downtowns of Oakley and Brentwood.

Balfour Road and State Route 4 intersection is currently signalized, resulting in significant backups during peak periods. This project will eliminate this at-grade intersection by building an interchange at this location.
