List of numbered roads in Middlesex County

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

Note: when London became a separated municipality and absorbed several nearby townships, the County Road designations for them disappeared, rendering them numberless. Many roads such as CR 37 (Highland Avenue) are now named only.

Many roads in Middlesex County were also formerly provincial highways, such as Highbury Avenue from Highway 401 (Exit 189) to current CR 2 (Formerly Highway 2), also known as the Wenige Expressway, and Exeter Road (Former Highway 135), turned back after Highway 402 was completed and rendered the road obsolete. Airport Road (Now named "Veterans Memorial Parkway", also Former Highway 100, a proposed beltway around London.. The other former highways were Highway 22, Highway 80, and Highway 81 (oddly enough, Highway 402 rendered Highways 22 and 81 obsolete upon its completion in 1981 as well. 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, Ontario is geographically quite large (by southern Ontario standards), and is quite important due to agriculture in the area.
