  • pavement resurfacing of Highway 400 from north of Dunlop Street to north of Sunnidale Road and from north of Bayfield Street to north of St. Vincent Street
  • Highway 400 median barrier replacement
  • drainage improvements within the resurfacing limits
  • installation of noise walls in the vicinity of Anne Street, Bayfield Street and Duckworth Street.

The scope of work includes:

  • Replacing the existing Sunnidale Road Underpass at Highway 400

  • Widening Sunnidale Road to accommodate future active transportation installed by other

  • Extending culvert C-78 and constructing a retaining wall to accommodate Highway 400 widening
  • Replacing median storm sewer and median barrier within Highway 400 reconstruction limits

At Dunlop Street, construction will include:

  • Replacing the existing Dunlop Street Underpass at Highway 400;
  • Lengthening the Dunlop Street Underpass to accommodate future widening of Highway 400 to 10 lanes;
  • Widening Dunlop Street Bridge to accommodate City of Barrie request.
  • Highway 400 pavement rehabilitation from south of Dunlop Street to south of Anne Street.
  • Re-configuration of the Highway 400 and Dunlop Street Interchange, including on-ramps, off-ramps, and intersections.
  • Installing a noise wall at the previously approved northbound on-ramp.
  • Replacement of two culverts under Highway 400 and various culverts within the Dunlop Street interchange.
  • Replacing median storm sewer and median barrier within Highway 400 reconstruction limits.

While work is expected to begin in 2023 on the Sunnidale Road bridge, MTO officials say the project is still waiting for funding, planning approvals, design, property acquisition and construction requirements. Utility relocation and any other preparatory works will begin in advance of construction.

Work began in June on a new interchange at Essa Road and Highway 400 to widen Essa Road to six lanes.
