Phase 2 will extend Highway 407 East approximately 22 kilometres from Harmony Road to Highway 35/115 in Clarington. The work also includes the addition of the 10-kilometre East Durham Link (EDL or Highway 418), which connects Highway 407 with Highway 401. There are eight interchanges as well, three of which are freeway-to-freeway.
Phase 2A of the project, running from Harmony Road to EDL, was completed in January 0f 2018. Phase 2B of the project, from the EDL to Highway 35/115 and including the EDL, is well underway. Paving, as well as work on bridges and other structures, continues to advance toward completion in line with the 2020 scheduled completion.
