Louis St. Laurent Ave.
Tremaine Rd. to Yates Blvd.

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).
