The traffic disruptions on the LaSalle Causeway will continue for a couple more days.
Public Services and Procurement Canada began what it calls routine annual inspections of the lift bridge on Monday.
The work includes checking structural, electrical and mechanical components of the bridge.
Lane reductions on the causeway between 9:30 a.m. and 8:30 p.m. will continue until Friday.
For boaters, there are scheduled lifts of the bridge at 8 a.m., noon, and 4 and 5 p.m.
