The speed limit has been lowered on St. Clair Parkway between Holt Line and Smith Line.
Coordinator of Engineering for St Clair Township Paul daSilva says a 50km/h construction zone has been set up as repairs are made to the McKeough Diversion Bridge.
Traffic will be down to an alternating single lane while work is completed..
He's hoping it can be wrapped up in six or seven weeks.
