ANTIOCH -- There are no full road closures planned for Highway 4 overnight this week, but local drivers still may want to plan on adjusting their routes.

On-ramps and off-ramps at the interchange will remain open, though turning movements will be limited.

During the day, a single lane in both directions of Somersville/Auto Center will be closed from 9 a.m. to 3 p.m. through Friday between Century Boulevard and Delta Fair Boulevard.

Also, a single southbound lane on Lone Tree Way/A Street will be closed from 8 a.m. to 2 p.m. through Friday from Texas Street/Bryan Avenue to Tregallas Road.

On the highway itself, one eastbound lane will be closed from 11 p.m. to 6 a.m. overnight Wednesday and Thursday and midnight to 6 a.m. Friday morning. A westbound lane on that same stretch will be closed from 10 p.m. to 4 a.m. overnight Wednesday and Thursday and 11 p.m. to 4 a.m. overnight Friday.
