Toronto Highway 407 Extension

407 East (2016-06-27) Aerial 110

Project Type: Design-Build / P3

Location: Toronto, Ontario

Owner: Ministry of Transportation, Ontario

Client: Ferrovial Agroman/SNC Lavalin

Construction Cost: $1 Billion

(JSE’s Portion: Section 3 - $650M)

Completion Date: 12/2016

This Public-Private Partnership (P3) project extends existing Highway 407E 24 km to the east in addition to adding a new north-south link connecting the extended 407E south to Highway 401. The project originates at Brock Road in Pickering, Ontario, and terminates at Harmony Road in Oshawa, Ontario. JSE provided proposals and bid plans for the Highway 407 portion of this P3 project. JSE also performed the final design for Section 3 which included the new West Durham Link, 407E, 401, and two multi-level full-speed directional interchanges. Four local streets were reconstructed to add overpasses.

Engineering calculations and analysis for the hydrology and hydraulics for every crossing were provided by JSE in accordance with the applicable highway and environmental standards. The structures were optimized to the smallest size possible in consideration of hydrology, hydraulics, and geomorphology.

JSE provided structural engineering services for the design of 48 highway bridges including steel beam and prestressed concrete superstructures in simple span and continuous arrangement. Most of the deck design utilized partial depth prestressed deck panels to expedite construction. A 3-span through girder rail bridge and single-span arch supporting a rail line were also included in the project.

Services included: road design, bridge design, traffic design, plan review, ATMS design, and hydraulic design for this complex, major new highway project. JSE also assisted with tolling design and utility coordination.
