King's Highway 48 - www.OntHighways.com

At the height on Highway 48's modern length, it ran from the Highway 401 interchange in Scarborough, northerly through Markham to Sutton. At Sutton, the highway made a 90 degree turn, and headed easterly to Coboconk (via a co-designation with Highway 12). In 1998, Highway 48 was downloaded from Vinegar Hill in Markham, southerly to Highway 401, in Scarborough. This decommissioned section is now known as Markham Road. Also in 1998, Highway 48 was decommissioned east of Highway 12 to Coboconk. This portion of Highway 48 is now known as Durham Highway 48, and Kawartha Lakes Road 48. In 2004, all Highway 48 shields were removed from Highway 12, thus eliminating the now redundant co-designation. In 2006, with the completion of Donald Cousens Parkway (formerly the Markham by-pass, Highway 48 was truncated at Major Mackenzie Drive in Markham. Highway 7 was also transferred between Highway 48 and Donald Cousens Parkway. Highway 48 now runs from Major Mackenzie Drive northerly to Highway 12 near Beaverton.

Road Info: Highway 48 is a very high standard, and also very busy highway. Despite being so busy, Highway 48 traffic along the route seems to flow well, at any given time of the day. Highway 48 between Markham and Beaverton is personal favourite route of mine, and I would recommend the route to any area roadgeek who is looking for a nice highway to drive. Highway 48 features a rural speed limit of 80km/h.
