Motorists who frequent the 406 in St. Catharines may want to find an alternate route for the month of May.
Both the north and south bound 406 are being subjected to a month long lane reduction to accomodate construction on the Burgoyne Bridge.
Southbound the right lane closes at 4th Avenue and the Northbound right lane closes just before Westchester.
Motorists should anticipate delays.
The closure is slated to last until May 31st.
