Concession for the design, construction, financing, operation and maintenance of a new 11 km highway that linked the 407 of Ontario (Canada) with the I-75 in Michigan (USA), consisted of three lanes in each direction, of which 8 km passed through a clearing site and the other three were built using the cut and fill process.

It consisted of an innovative 6-lane, 11-kilometre highway that offered benefits for transport, green spaces, recreational trails and community connections.

Traffic management during construction and phase scheduling had been of great importance due to the need to maintain traffic along the existing highway, Highway 3, which will be progressively diverted to allow for the construction of the main highway, Highway 401.

COMMUNITY BENEFITS

  • The Parkway enables the safe and efficient movement of people, goods and services along route 401.
  • Separats local and international traffic.
  • It has eliminated intermittent traffic in residential areas along its route.
  • In the near future, the Parkway will connect the 401 directly to a new Canadian inspection site and the Gordie Howe International Bridge.

GENERAL INFORMATION

  • Location: Windsor, Ontario, Canada.
  • Contract type: Design, construction, financing, operation and maintenance (PPP) for a 30 year period.
  • Infrastructure: An 11 km highway consisted of three lanes in each direction, plus a 2+2 road that intersected with the main road and served the adjoining streets. The project consisted of 12 cut-and-cover tunnels, 12 overpasses, 34 km² of retaining walls and 41 km² of acoustic screens.
  • Year of project completion: 2015

KEY ASPECTS

This was the largest investment in history for a highway project in the Canadian province of Ontario.

The Rt. Hon. Herb Gray Parkway included three essential components:

  • A six-lane extension of Highway 401 that stretched below the level from the area west of the North Talbot Road Bridge to EC Row Expressway, and then parallel to EC Row Expressway until Ojibway Parkway.
  • A four-lane extension of Highway 3 that included the multi-lane roundabout towards the EC Row Highway area, where was joined Huron Church Road.
  • The Parkway Trail, which spaned approximately 17 kilometres, was located within 120 hectares (300 acres) of green space adjacent to the two stretches of roads and through the 11 peaks of the tunnel.
