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.
