The Project includes the 52-kilometre (km) Highway 413 corridor, a 4 km extension to Highway 410, and a 3 km extension to Highway 427 (both facilitating connection to the Highway 413 corridor), for a total of 59 km of new infrastructure.

The highway will have 11 interchanges at municipal roads. Features such as service centres, carpool lots, truck inspection stations, and the potential for electric vehicle charging stations, have been explored as part of Preliminary Design.

The transitway will be a separate corridor running alongside the highway, dedicated for public transit, which will be subject to a separate Environmental Assessment (EA).

The Preferred Alignment

Highway 413 would extend from Highway 400, between King Road and Kirby Road, to the 401/407 ETR interchange near Mississauga, Milton and Halton Hills.
