The California Department of Transportation (Caltrans) and the Contra Costa Transportation Authority (CCTA) are widening State Route 4 (SR-4) through Pittsburg and Antioch. As part of this construction work, the contractor will be installing drainage ditch alongside the highway at Contra Loma Boulevard.

In order to ensure crew and public safety during this work, the contractor will close all lanes of SR-4 in the eastbound direction from Contra Loma Boulevard to Lone Tree Way/A Street on the mornings of Thursday August 14 and Friday August 16 from 12:01 am to 4:00 am. And again on the morning of Saturday, August 16 from 2:00 am until 6:00 am.

The detour for this work will be as follows:

o Eastbound motorists will be directed off the highway at the Contra Loma Boulevard off-ramp and left onto Fitzuren Road, right onto G Street, left onto Putnam Street, and then left onto Lone Tree Way and then onto the EB on-ramp.

The Highway 4 projects include improvements to the entire project corridor that will help revitalize eastern Contra Costa County. The projects expand Highway 4 from four to eight lanes between Loveridge Road and SR-160, and add a BART extension from Pittsburg to Antioch (eBART). The projects will also expand the highway from two to four lanes from Lone Tree Way to Balfour Road. This will greatly improve transit accessibility for the region and help reduce traffic congestion and enhance the quality of life for the more than 250,000 residents of eastern Contra Costa County. The projects have been carefully staged to keep 130,000 vehicles per day moving as major construction and demolition work continue, and include over $1.3 billion in State, Federal, Regional Bridge Toll, and Contra Costa Measures C & J sales tax funds.

Caltrans and CCTA appreciate your patience as we work to improve the highways. For the most current information on all Highway 4 corridor closures please visit our website at: http://4eastcounty.org.
