Louis St. Laurent Ave.
Tremaine Rd. to James Snow Parkway

Louis St. Laurent Ave. is an important roadway that, once complete, will provide an essential corridor linking east and west Milton, from Tremaine Rd. through to James Snow Parkway.

It will also provide residents in residential growth areas with more direct access to major highways such as the 401 and 407.

The completed roadway will intersect all three residential growth areas known as the Bristol Survey (to the north, on the eastern portion of the roadway), Sherwood Survey (to the north, on the western portion of the roadway) and Boyne Survey (to the south, along the entire roadway).

Project Phases

The roadway is being designed as a four-lane thoroughfare with a centre median.

Phase 1 - Regional Road 25 to Yates Blvd.

  • Construction of two westbound traffic lanes, storm sewers, and curbs
  • Construction of a multi-purpose trail in the north boulevard
  • Construction of north bridge over 16 Mile Creek

Phase 2 - Bronte Street to Regional Road 25

  • Construction of westbound traffic lanes including storm sewers, curbs and on-road bike lane

Phase 3 - CN Rail Overpass West of Bronte Street

  • Design and building of a four-lane railway overpass including centre median, on-road bike lane, curbs, trail-way and sidewalks

Phase 4 - Tremaine Road to Regional Road 25

  • Construction of four traffic lanes including storm sewers, curbs, on-road bike lanes from Tremaine Road to Bronte Street
