SR 4 Sand Creek Rd. Interchange and 4-Lane Widening

The Sand Creek Road Interchange Project will widen SR4 from 2 to 4 lanes (2 in each direction) from Lone Tree Way to Sand Creek Road.  The project also includes the construction of the Sand Creek Road Interchange and will provide a median wide enough to accommodate mass transit.

These improvements will result in much needed congestion relief and improve mobility for the residents of East Contra Costa County.

Contractor: Bay Cities/Myers, Joint Venture

Construction began in June 2012.  Estimated date of completion is Spring 2014.
