Assemblymember Grayson Announces State Funding for I-680/SR 4 Interchange Improvements

Thursday, May 17, 2018

(Concord, CA) Assemblymember Timothy S. Grayson (D-Concord) announced that the California Transportation Commission (CTC) has approved $34 million in funding for improvements of the Interstate 680 / State Route 4 highway interchange in Concord, one of the most congested freeway interchanges in the Bay Area.

“Anyone who has driven in the East Bay knows this interchange is notorious for gridlock, which is why I have been working for more than a year with the CTC, Department of Transportation, and Contra Costa Transportation Authority to secure the funding needed to get this project started,” Assemblymember Grayson said. “As a critical artery for the region, it is incumbent on us to ensure the conditions of this interchange are improved so commuters are able to navigate this interchange without the additional stress caused by standstill traffic and bottlenecks. I applaud the CTC for funding this project so that the people of my district, and the East Bay Area, will be able to spend less time sitting in traffic and more time at home with their families.”

The I-680/SR4 Interchange connects a major north-south thoroughfare for Solano, Contra Costa, and Alameda Counties with the main east-west artery for Contra Costa County. In its review, the Commission concluded the existing I-680/SR 4 interchange has deficiencies that contribute to heavy traffic congestion and inefficient traffic operations. This project, one of several phases of improvements planned by the Contra Costa Transportation Authority for Highway 4, will construct almost 10 miles of new traffic lanes to ease congestion and will retrofit bridges to meet seismic standards as well as extend on-ramps to improve traffic safety. CCTA was awarded the funding through the CTC’s competitive Local Partnership Program.
