ANTIOCH -- Drivers on Highway 4 should expect delays this weekend as construction work will close all lanes in the early-morning hours Sunday.

Highway 4 will be closed between Contra Loma Boulevard and Lone Tree Way on Sunday morning from midnight to 6 a.m. westbound and 1 to 7 a.m. eastbound.
Westbound drivers will be detoured off the highway at Lone Tree to 18th Street and back on the freeway at L Street. Eastbound motorists will be detoured off the road at Contra Loma and down Fitzuren Road and Putnam Street to Lone Tree.
Motorists are advised to expect delays and allow extra time for their commute.
