Highway 407 East Extension



The Ontario Ministry of Transportation (MTO) is proposing to construct an easterly extension of the 407 Transportation Corridor (highway/transitway). The undertaking would consist of a highway and transitway, including the extension of mainline 407 from its current terminus at Brock Road to Highway 35/115 and two north-south links connecting Highway 401 to the proposed extension of Highway 407.

The MTO completed an Environmental Assessment (EA) regarding the extension of Highway 407 east of Brock Road in Pickering to Highway 115, as well as two freeway links from Highway 401 to Highway 407, in east and west Durham. The EA Report was sent to and approved by the Ministry of Environment in June 2010.

On March 21, 2012 the Ministry of Transportation and Infrastructure Ontario announced that the 407 East Development Group is the preferred bidder to design, build, finance and maintain Phase 1 of the Highway 407 East project.

The consortium's key members include Cintra Infraestructuras S. A. and SNC-Lavalin.  

Highway 407 East will be built in two phases. Phase 1 includes the mainline from Brock Road in Pickering to Harmony Road in Oshawa and the West Durham Link in Whitby. Phase 2 includes the mainline from Harmony Road in Oshawa to 35/115 in Clarington and the East Durham Link in Clarington. Phase 1 will be constructed by 2015 and Phase 2 will be constructed by 2020 with an interim opening from Harmony Road to Taunton Road at the East Durham Link by 2017.
