Ontario Highway 412
King's Highway 412, or simply Highway 412, is a controlled-access highway and former tolled highway in the Canadian province of Ontario. The route is long, connecting Highway 401 with the eastern extension of Highway 407. The route lies entirely within Whitby in the Regional Municipality of Durham, travelling within one kilometre of the border between Whitby and Ajax and Pickering (Lake Ridge Road). During planning, the route was known as the West Durham Link. Its designation as Highway 412, the first new 400-series designation in several decades, was confirmed along with Highway 418 on February 6, 2015. Although initially planned to open in October 2015, the opening was delayed until June 20, 2016. Highway 412 opened alongside the extension of Highway 407 (Highway 407E) from Brock Road in Pickering to Harmony Road in Oshawa. The Ministry of Transportation of Ontario (MTO) thus decided to compensate for delays by waiving all tolls until February 1, 2017. On April 5, 2022, Highway 412 became toll-free. Route description Highway 412 is an four-lane highway extending from Highway 401 to Highway 407E, just north of Highway 7. The entire length of the route lies between Lakeridge Road and Coronation Road, within Whitby. At the
