Highway 401 Information Centre

One of the three components of the Rt. Hon. Herb Gray Parkway (the Parkway) is an extension of Highway 401 that runs below-grade from the area west of the North Talbot Road Bridge to E.C. Row Expressway and then parallel to E.C. Row Expressway to Ojibway Parkway.

As part of construction staging, a portion of the below-grade Highway 401 between North Talbot Road Bridge and Labelle Street opened to both westbound and eastbound traffic on June 29, 2015. The remaining section of Highway 401 opened on November 21, 2015.

Border-bound Highway 401 Traffic

Travellers originating on Highway 401 or travellers who enter below-grade Highway 401 from a Parkway on-ramp and are destined for the Canada-U.S. border will continue along Highway 401 within the Parkway corridor, exit at the westbound Highway 401 off-ramp to Highway 3/Huron Church Road and continue on Huron Church Road northbound toward existing border crossings.

Ramps

There are 21 westbound and eastbound on-ramps and off-ramps within the Parkway corridor that connect at-grade Highway 3 to below-grade Highway 401. On-ramps originate on Highway 3 or on municipal roads and travel to Highway 401. Off-ramps originate on Highway 401 and travel to Highway 3 or municipal roads.
