​Dunlop Street Bridge Sanitary Relocation

Sarjeant Drive to Anne Street

To facilitate the Ministry of Transportation's (MTO) Dunlop Street Bridge Interchange project works planned for the future, the City of Barrie will be relocating the existing trunk sanitary sewer.

The existing alignment crosses Dunlop on the west side of the bridge and then crosses Highway 400 south of the bridge. The existing alignment conflicts with MTO’s future bridge structure. MTO requires the City to move the sewer so they can construct the new Dunlop Street Bridge.

The City has awarded the Engineering Design of the Dunlop Street Trunk Sanitary Relocation to Associated Engineering and is currently in the design phase of the project.

Project Scope

It has been confirmed that the scope of works will include relocating the trunk sanitary sewer along Cedar Point Drive from Dunlop to Edgehill and abandon the existing sewer abutting the Highway 400 right of way. The sewer will cross Highway 400 south of the existing interchange and connect to the existing main at Hart Drive.
