Lane Opening on State Route 4 to get Eastbound Commuters Home Faster
New lane added as part of the highway widening project

Contra Costa County - The Highway 4 Project is set to hit another milestone on Saturday November 21 with the opening of one new lane of traffic on East Bound (EB) Highway 4. The additional lane starts at the Loveridge Road overcrossing in Pittsburg, and extends to the A Street undercrossing in Antioch. Commuters will be able to travel EB using the additional lane, adding up to 50% more capacity along this segment. This follows the early November opening of an additional two westbound lanes, doubling the westbound capacity, from A Street to Contra Loma Blvd. The project also includes newly configured on- and off-ramps from the highway to local roads.

Construction on the Contra Loma Boulevard / G Street segment began in March of 2012. The construction budget for this segment was $48.7 million. Of that, $10.8 million was funded by CMIA Proposition 1B, approved by California voters in 2006. The improvements made possible by this bond measure are relieving congestion, facilitating movement of goods, improving air quality and enhancing the safety of the State’s Transportation system.

"The opening of another lane through the Contra Loma and G Street Interchanges brings additional capacity to the Highway 4 corridor, which will help smooth the traffic flow and increase mobility for the residents and businesses in East Contra Costa County,” said Bijan Sartipi, Caltrans District 4 Director.

The EB State Route 4 on ramp from Contra Loma Blvd. is not yet open, but work on this is anticipated to be finished in early 2016, as part of the Lone Tree / A Street interchange project.
