Highway 401 Expansion – Mississauga to Milton, Ontario

Client: Ministry of Transportation Ontario (MTO) and Infrastructure Ontario (IO)
Completed: 2023
Project Value: $750 Million

The Highway 401 Project involved the widening and reconstruction of approximately 18 km of highway in each direction from 6 lanes to 10 to 12 lanes to facilitate high-occupancy vehicle median lanes in the western Greater Toronto Area (GTA), from east of the Credit River in Mississauga to west of Regional Road 25 in Milton.

Amico was a member of West Corridor Constructors (Amico, Aecon, Parsons) (WCC); the team selected by IO and MTO to design, build and finance the Project under a Public Private Partnership (P3) approach.

The multi-lane expansion will help fight gridlock and keep goods and people moving across the Greater Golden Horseshoe. The project will allow 25 years of growth, and the reduced daily travel time, traffic congestion, reduced traffic on local roads, greenhouse gases, and fuel consumption will improve the quality of life for commuters.

As an Equity and Design-Build joint venture consortium member of WCC, Amico’s scope of work included Full Construction/Project Management Services, Health & Safety, Environment and Quality Management, Utilities, and Third-Party Interfacing; Public and Stakeholder Engagement; and Permitting and Approvals. Design and Construction of horizontal/vertical infrastructure improvements, interchanges, and underpass/overpass structures to OPS standards; and development and implementation of complex traffic control and construction staging.

The scope of work also included modifications to existing infrastructure to accommodate the proposed widening, including nine new, replaced, or widened bridges, five bridge rehabilitations, retaining wall rehabilitation and seven culvert replacements, extensions or rehabilitations, utility work, and ecological restoration.
