History of King's Highway 80:

King's Highway 80 was a minor collector highway which linked Highway 2 at Strathburn to Highway 40 and Courtright in the Sarnia area. The highway was first designated in 1937, and it existed up until the late 1990s when the route was downloaded in its entirety to the Counties of Lambton and Middlesex.

Highway 80 was first designated as a provincial highway on August 11, 1937, at a length of 21 km. Originally, Highway 80 ran from Highway 2 at Strathburn to Highway 79 in Alvinston. Even before Highway 80 was assumed, the road was paved between Highway 2 and Glencoe. However, the rest of the highway from Glencoe to Alvinston was gravel-surfaced. In 1956, Highway 80 was paved from Glencoe to Walker's Corners. Highway 80 was relocated south of Alvinston in the early 1960s, in order to bypass the meandering original highway alignment between Alvinston and Walker's Corners. The new route of Highway 80 bypassed Alvinston and provided a more direct link to Highway 79. The new route of Highway 80 from Highway 79 to Walker's Corners was completed in 1960 and was paved in 1961. The original 1930s alignment of Highway 80 followed Gardner Trail, Lobelia Drive and Conservation Drive. In 1963, Highway 80 was extended westerly from Highway 79 to Courtright. The extension added another 49 km to the length of Highway 80.

On March 31, 1997, the entire route of Highway 80 was decommissioned as a King's Highway. Ownership of the road was transferred to the Counties of Lambton and Middlesex. Former Highway 80 is now officially known as Lambton Road 80 and Middlesex Road 80, but the route is still commonly referred to as "Highway 80" by many motorists. Services are surprisingly scarce on Highway 80. They are generally only available in larger towns and communities along the highway. Unless posted otherwise, the speed limit on Highway 80 is 90 km/h (55 mph). Please visit the Highway 80 Mileage Chart page for a list of mileage reference points along Highway 80.
