The Ministry of Transportation (MTO) has informed the Ontario Trucking Association that Stantec Consulting Ltd. will be conducting the Preliminary Design, Detail Design and Class Environmental Assessment Study (Class EA) for improvements to Highway 3 from Highway 4 to Centennial Avenue (St. Thomas). This is related to the advanced municipal utility and storm sewer relocations that are necessary for the twinning of Highway 3 through St Thomas.
This work will result in the temporary closure of Highway 3 throughout two stages of the project:
- Stage 1: Temporary full closure of Highway 3 from First Avenue to Centennial Avenue, including temporary full closure of the eastbound on-ramp and westbound off-ramp at First Avenue Interchange
- Stage 2: Temporary full closure of Highway 3 from Wellington Road to First Avenue, including temporary full closure of the westbound on-ramp and eastbound off-ramp at First Avenue Interchange
Along with the closures to Highway 3, the municipal roads Hughes Street, Woodworth Street, Flex O Lite Road, Burwell Road, Gaylord Road, Harwill Road and Harper Road may also be required to be closed temporarily.
The planned detour route will include Wellington Road, Ron McNeil Line and Highbury Avenue South/Centennial Avenue. The detour route can be seen in the map below:
The work is expected to begin in June 2026 and be completed in 2026.
