The Highway 4 Widening Project continues to achieve notable progress thanks to the opening of new lanes of traffic on eastbound and westbound Highway 4 at Hillcrest Avenue in Antioch. The eastbound lanes at Hillcrest Avenue were opened to traffic on Sunday, May 1, with the westbound lanes opening yesterday, Thursday, May 5.
These lane openings are a significant milestone in the Highway 4 Widening Project as now all westbound highway lanes for the entire corridor are open to traffic.
“We want to thank the public for their patience. The Highway 4 Widening Project is vitally important to East County and the greater Bay Area in terms of mobility, economic revitalization, and, in the longer term, multi-modal options for 250,000 East County residents,” said CCTA Executive Director Randy Iwasaki. “Because we have been carefully staging the work to occur at night, and opening each section of the widening project as it is completed, we have also been able to provide incremental congestion relief on this heavily used corridor, without any loss of capacity.”
The purpose of the $1 billion overall project is to improve traffic flow and motorist safety along a 10-mile stretch of freeway between Pittsburg and Antioch. Work at Hillcrest Avenue also includes the construction of a new BART station in Antioch.
“The improvements to Highway 4 that are brought about with this project and through this partnership are a benefit to every driver that has experienced the traffic congestion on this corridor,” said Caltrans District 4 Director Bijan Sartipi. “We look forward to crossing the finish line later this summer and giving the new and improved Highway 4 back to the residents of East Contra Costa County and all motorists.”
