Construction crews are making steady progress on the Dunlop Street underpass project in Barrie, according to a recent update from the city. The project, which involves replacing the existing bridge and creating a new underpass, is part of a broader effort to improve traffic flow and pedestrian safety in the downtown area.
Project Overview
The Dunlop Street Bridge Replacement project began earlier this year and is expected to be completed by late 2026. The new underpass will allow vehicles to pass beneath the railway tracks, eliminating the need for a level crossing and reducing traffic delays. Pedestrian walkways and cycling lanes are also being incorporated into the design.
Current Construction Status
Crews have completed the demolition of the old bridge and are now working on excavation and foundation work for the new underpass. Steel reinforcement and concrete pouring are ongoing. The city reports that the project remains on schedule and within budget.
- Demolition of old bridge: Completed
- Excavation and foundation work: In progress
- Steel reinforcement and concrete pouring: Ongoing
- Expected completion: Late 2026
Traffic Impacts
During construction, Dunlop Street remains closed between Maple Avenue and Mulcaster Street. Detour routes are in place, and drivers are advised to allow extra travel time. Pedestrian access to businesses is maintained via temporary walkways.
Community Benefits
Once complete, the underpass is expected to significantly reduce congestion and improve safety for pedestrians and cyclists. The project also supports economic development by improving access to downtown Barrie.
