Contra Loma Blvd and L Street to close this week for Highway 4 widening

As part of the Highway 4 (SR-4) widening construction work, the contractor is demolishing the inactive portion of the existing SR-4 bridge structure over Contra Loma Boulevard/L Street. In order to ensure crew and public

safety during this work, the contractor will close all lanes of Contra Loma Boulevard/L Street in the northbound and southbound directions between the westbound SR-4 on-ramp and the eastbound SR-4 off-ramp on Thursday and Friday evenings, May 16-17 from 11:59 pm to 5:00 am, and if necessary Monday and Tuesday evenings, May 20-21 from 11:59 pm to 5:00 am.

The detours for this work will be as follows:

o Northbound motorists will be directed right on Fitzuren Road, left on G Street, left on 18th Street, left on L Street, right on westbound SR-4 on-ramp. Motorists will have the option to turn right onto L Street from 18th Street.

o Southbound motorists will be directed right on westbound SR-4 on-ramp, exit on Somersville Road loop off-ramp, right on Somersville Road, left on Delta Fair Boulevard, left on Buchanan Road, straight to Contra Loma Boulevard.

The SR-4 Widening Project includes over $540 million in State, Federal, and Contra Costa Measure J sales tax, and other local funds to widen SR-4 from four to eight lanes between Loveridge Road and SR-160. The combined effort of Caltrans and the Contra Costa Transportation Authority on projects in the SR-4 corridor will reduce congestion, create a safer roadway, improve operations, and reduce traffic delays on this important east-west connector. When completed, the SR-4 highway median will be used to extend BART service from Pittsburg/Bay Point to a new Antioch station at Hillcrest Avenue. Caltrans and CCTA appreciate your patience as we work to improve the highways. For the most current information on all SR-4 corridor closures please visit our website at: http://4eastcounty.org.
