November 3, 2015: The Highway 4 Project hit another milestone this week with the opening of two new lanes of traffic on westbound Highway 4, starting just after the Lone Tree Way/A Street undercrossing. Commuters can now travel along four lanes of highway, including a High Occupancy Vehicle lane. The project also includes newly configured on- and off-ramps from the highway to local roads.
See diagrams of the new lane segments on the Contra Loma Boulevard segment web page.
The auxiliary lane and off-ramp to Contra Loma Boulevard are not yet open, but they are expected to be open in the next week. The Contra Costa Transportation Authority (CCTA) and Caltrans are working together to complete this segment of the Highway 4 corridor project, referred to as Contra Loma Boulevard/L Street, of the highway construction project.
The purpose of the overall Highway 4 corridor project is to improve traffic flow on the highway and enhance motorist safety.
“We’re very happy to be able to open these new lanes to traffic and bring additional congestion relief to Eastern Contra Costa County,” said Ivan Ramirez, Construction Manager, CCTA. “This is the third of five segments we’ve opened to the public for the Highway 4 corridor project, and we’ll continue to work hard to finish the next two to deliver a modernized Highway 4 to the public.”
“Caltrans is glad to work with our partner in this growing community in East Contra Costa County,” said Dan McElhinney, Caltrans Chief Duputy District Director. “Anything we can do to help meet the traffic demand is beneficial for the cities along this corridor and the entire Bay Area region.”
Construction on the Contra Loma Boulevard/L Street segment began in March of 2012. The eastbound lanes for the segment are expected to open in late November or early December.
The construction budget for this segment was $48.7 million. For more information, please visit our website at www.4eastcounty.org
