Railway construction will once again cause some traffic headaches for drivers in Chatham.

The Municipality of Chatham-Kent said Queen Street and William Street South will be closed to traffic at their respective railway crossing for rehabilitation beginning on Wednesday at 7 a.m.

The closures will remain in place until 5 p.m. on Thursday.

Detour signs will be in place to guide drivers around the closures and emergency vehicles will not have access through the work zone.

Queen Street and William Street South were previously closed from February 19-23 to allow CN Rail to upgrade its railway warning system.
