TORONTO - The Liberal government is stepping up the schedule for extending Highway 407 east from Brock Road in Pickering to Harmony Road in Oshawa by 2015.

The toll highway will be extended east to link up with Highways 35-115 by 2020.

There will also be 10 kilometres of north-south highway, the West Durham Link, to connect Highway 407 East and Highway 401 by 2015.

The government says extending the first phase to Harmony Road in Oshawa instead of ending it at Simcoe Street will ease congestion on city streets.

Residents in the Peterborough area have been pressing the Ontario government for years to speed up extension of the 407 to Highways 35-115.

The Tories say the extension of Highway 407 east to Highways 35-115 was supposed to be completed by 2013.
