The BART strike, which has altered travel plans for many East Contra Costa commuters, may also chip into planned overnight construction work this week on Highway 4.

Plans call for all eastbound lanes to be closed between Pittsburg's Loveridge Road and the Somersville Road/Auto Center Drive exit in Antioch from 1 to 5 a.m. However, the contractor will stop work an hour earlier if the BART strike is ongoing, Contra Costa Transportation Authority officials said in a news release.

All eastbound lanes Somersville/Auto Center and Lone Tree Way/A Street will be closed 1 to 6 a.m. Saturday.

A single lane closure eastbound direction between Contra Loma Boulevard/L Street and Hillcrest Avenue from 11 p.m. to 6 a.m. overnight Wednesday through Friday, and 4 a.m. if the strike continues.

The closure of the eastbound Loveridge on-ramp Thursday would also end at 4 a.m., instead of 5 a.m.

The eastbound on-ramp from Loveridge Road will be closed on Thursday morning.

Locally, all lanes of Somersville/Auto Center will be closed where it crosses under Highway 4 from 10 p.m. to 5 a.m. overnight Monday through Friday.

A single lane of that stretch will be closed from 9 a.m. to 3 p.m. during the week.
