Loveridge Road ramps to close for Highway 4 construction

As part of the construction work to widen Highwy 4 (SR-4), the contractor will be constructing the westbound off-ramp to Loveridge Road and the westbound on-ramp from Loveridge Road to SR-4. In order to ensure crew and public safety during this work, the contractor will close the westbound on-ramp from Loveridge Road to SR-4 beginning Friday evening May 10 at 10:00 pm until Monday morning May 13 at 4:00 am. The contractor will also close the westbound off-ramp to Loveridge Road on Friday through Sunday evenings from 6:30 pm to 9:30 am.

The detour for the westbound on-ramp from Loveridge Road to SR-4 closure will be as follows:

o Motorists from Loveridge Road will be directed west on California Avenue, straight onto westbound onramp from Railroad Avenue to SR-4. For detour map, please see attachment.

o Motorists from eastbound California Avenue will be directed right on Loveridge Road, right on Leland Road, right on Railroad Avenue, and left onto the westbound on-ramp to SR-4. For detour map, please see attachment.

Drivers on westbound SR-4 who want to exit the highway may use alternate off-ramps at Somersville Road or Harbor Street/Railroad Avenue. Trucks are advised to use the Somersville Road off-ramp.

Motorists are advised to expect delays and allow extra time for their commute. Please drive with caution through the detours and leave a safe traveling distance between your vehicle and the vehicle ahead of you.

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
