History of King's Highway 427:

King's Highway 427 is an urban freeway which forms an important north-south highway link through the City of Toronto. The highway primarily serves as a commuter route, connecting the Queen Elizabeth Way (QEW) and the Gardiner Expressway to Highway 401 and Highway 407. The highway was created in 1972 when the existing Highway 27 Freeway through Etobicoke was redesignated as Highway 427. In the early 1970s, Highway 427 was linked to the Airport Expressway leading to Toronto International Airport through an extensive reconstruction of the Highway 401 and Highway 427 Interchange. During the 1970s and 1980s, Highway 427 was extended north from Toronto International Airport towards Highway 50 (Albion Road) by upgrading a local collector road known as Indian Line to a freeway. The final section of Highway 427 was completed from Highway 50 to Highway 7 near Woodbridge in the 1990s. The Highway 427 Extension project was carried out in conjunction with the construction of Highway 407. In addition, two at-grade intersections along Highway 427 at Morning Star Drive and the ramp to Eastbound Highway 409 were closed off and replaced by grade separations during the 1990s. Planning is now underway to widen Highway 427 from Highway 409 to Highway 407. This expansion project will see the implementation of two High-Occupancy Vehicle (HOV) Carpool Lanes (one lane in each direction) on Highway 427. The lanes are expected to be operational sometime after 2014, providing that planning, design and funding remain on schedule.

The Ministry of Transportation (MTO) is planning to extend Highway 427 from its current northern terminus at Highway 7 towards the Bolton area. The Ontario Government's Growth Plan for the Greater Golden Horseshoe has identified the need for a new east-west transportation corridor from Guelph to Vaughan, passing just to the north of Brampton. The exact route for this future east-west transportation corridor has not yet been finalized. However, it is certain that Highway 427 will be extended to meet this new east-west corridor once a final route has been selected, as the Highway 427 Extension is identified as a necessary highway expansion in the Growth Plan. The new Highway 427 Extension will add approximately 10 km to the highway's length. No construction schedule has been established for the Highway 427 Extension, since the road is still in the planning stages.

Highway 427 varies in width from 12 to 16 through lanes (six to eight lanes per direction) from the QEW to Highway 401. This section of Highway 427 features an Express-Collector Lane configuration. Most sections of Highway 427 north of Highway 401 are six through lanes, but a short section near Pearson Airport has ten lanes. The highway's cross section is also reduced to four through lanes through several major interchanges. Due to Highway 427's short length, there are no Service Centres located along the highway. However, services are readily available at all interchanges. Unless posted otherwise, the speed limit on Highway 427 is 100 km/h (60 mph). Exits along Highway 427 are not numbered, but distances along the highway can be calculated by visiting the Highway 427 Mileage Chart page.
