List of numbered roads in Middlesex County, Ontario

Last updated

This page lists all of the numbered county roads in Middlesex County, Ontario.

Note: when London became a separated municipality and absorbed Westminster Township, numbered County Roads in the township lost their designation. Many roads such as the former County Road 37 (Highland Avenue) are now named only.

Several roads near London were formerly provincial highways, but were not renumbered as County Roads when the highway designation was dropped.

The reason for this somewhat high concentration of former provincially controlled roads in this county is due to London's size (roughly 340,000), as it is the anchor for Southwestern Ontario, and Middlesex County is geographically quite large (by southern Ontario standards), and is quite important due to agriculture in the area.

The Ontario Provincial Highway Network consists of all the roads in Ontario maintained by the Ministry of Transportation of Ontario (MTO), including those designated as part of the King's Highway, secondary highways, and tertiary roads. Components of the system—comprising 16,900 kilometres (10,500 mi) of roads and 2,880 bridges —range in scale from Highway 401, the busiest highway in North America, to unpaved forestry and mining access roads. The longest highway is nearly 2,000 kilometres (1,200 mi) long, while the shortest is less than a kilometre. Some roads are unsigned highways, lacking signage to indicate their maintenance by the MTO; these may be remnants of highways that are still under provincial control whose designations were decommissioned, roadway segments left over from realignment projects, or proposed highway corridors.

King's Highway 4, also known as Highway 4, is a provincially maintained highway in the Canadian province of Ontario. Originally much longer than its present 100.8 km (62.6 mi) length, more than half of Highway 4 was transferred to the responsibility of local governments in 1998.

<span class="mw-page-title-main">Ontario Highway 7</span> Ontario provincial highway

King's Highway 7, commonly referred to as Highway 7 and historically as the Northern Highway, is a provincially maintained highway in the Canadian province of Ontario. At its peak, Highway 7 measured 716 km (445 mi) in length, stretching from Highway 40 east of Sarnia in Southwestern Ontario to Highway 17 west of Ottawa in Eastern Ontario. However, due in part to the construction of Highways 402 and 407, the province transferred the sections of Highway 7 west of London and through the Greater Toronto Area to county and regional jurisdiction. The highway is now 535.7 km (332.9 mi) long; the western segment begins at Highway 4 north of London and extends 154.1 km (95.8 mi) to Georgetown, while the eastern segment begins at Donald Cousens Parkway in Markham and extends 381.6 km (237.1 mi) to Highway 417 in Ottawa.

Highbury Avenue is an arterial road and municipal expressway located in the Canadian province of Ontario. In addition to serving as a primary north–south thoroughfare in eastern London – through which part of it is a limited-access freeway – the road also provides access to Highway 401 and continues south to St. Thomas. The southern terminus of Highbury Avenue is an intersection with South Edgeware Road, just north of Highway 3 and the eastern end of the St. Thomas Expressway. From there, it travels 45.6 kilometres (28.3 mi) north to Highway 7, east of Elginfield. Outside of London and St. Thomas, the road also passes through the communities of Ballymote and Bryanston. It is designated as Elgin County Road 30 within Central Elgin, and as Middlesex County Road 23 within Middlesex Centre, the two rural municipalities through which the route passes.

King's Highway 27, commonly referred to as Highway 27, is a provincially maintained highway in the Canadian province of Ontario. The Ministry of Transportation of Ontario was once responsible for the length of the route, when it ran from Long Branch to Highway 93 in Waverley. Highway 27 followed a mostly straight route throughout its length, as it passed through the suburbs of Toronto, then north of Kleinburg the vast majority of the highway was surrounded by rural farmland. Today, only the southernmost 1.6 km (1 mi) from Highway 427 north to Mimico Creek is under provincial jurisdiction, the remainder of the route is maintained by the city of Toronto, York Region and Simcoe County.

At the beginning of 1998, the entire highway was transferred to the municipalities of Frontenac County through which it travelled: Kingston, South Frontenac and Central Frontenac.
