ANTIOCH, CA — The California Department of Transportation (Caltrans) and the Contra Costa Transportation Authority (CCTA) are constructing two new connector ramps, one connecting westbound SR-4 to northbound SR-160, and one connecting southbound SR-160 to eastbound Highway 4. This construction work will require two full nighttime closures of westbound SR-4, between Laurel Road and the SR-160 on-ramp:
The closures will occur between 10 p.m. and 4 a.m. on Tuesday, June 3 and Wednesday, June 4. This work is being performed at night in order to minimize impacts to the motoring public. Signage will be in place indicating detour routes during these closures. Please see the attached maps for the detour routes. Motorists are urged to drive slowly in the cone zone.
The Highway 4 projects include improvements that will help revitalize eastern Contra Costa County. The projects expand Highway 4 from four to eight lanes between Loveridge Road and SR-160, add two connector ramps between Highway 4 and Highway 160, and add a BART extension from Pittsburg to Antioch (eBART). 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, Contra Costa Measure C & J sales tax, regional bridge tolls, and other local funds.
Caltrans and CCTA appreciate your patience as we work to improve the highways. For themost current information on all SR-4 corridor closures please visit our website at: http://4eastcounty.org
