Public Works crews will begin work today to replace the King Street Bridge over Kenilworth Avenue.
Lane restrictions and a 20 tonne load limit were placed on the bridge last fall due to concerns with loose surface concrete.
The Kenilworth Access will remain open and signed detours will be in place to guide you around the construction area.
HSR routes 5-Delaware and 41-Mohawk will also be on detour during the construction period.
The project is expected to be completed by the end of December.
