History of King's Highway 412 (Toll):
This new freeway connects Highway 401 to Highway 407 (Toll) in Whitby. After being referred to as the "West Durham Link" for many years during planning and early phases of construction, the Ontario Ministry of Transportation formally announced their decision to number the new freeway as Highway 412 on February 5, 2015. Unlike the Highway 407 Express Toll Route (ETR), Highway 412 will be a publicly-owned toll highway. Highway 412 will form a much-needed north-south link between Highway 401 and Highway 407 (Toll). Highway 412 officially opened to traffic on June 20, 2016. Tolls will not be collected on this route, or on Highway 407 (Toll) east of Brock Road, until early 2017.
