King's Highway18, commonly referred to as Highway18, was a provincially maintained highway in the Canadian province of Ontario, located entirely within Essex County. Since 1998, the majority of the former route has been known as Essex County Road20. The route travelled at the southernmost point in Canada, along or near the shoreline of the Detroit River and Lake Erie between Windsor and Leamington, with Highway 3 as the terminus at both ends. The former route provides access to the communities of LaSalle, Amherstburg, Malden Centre, Harrow, Kingsville and Union.
The original alignment of Highway18 followed a completely different routing for the first 18months of its existence than it would for the following 50years. As it was first designated in 1930, Highway18 provided a shortcut between Windsor and Tilbury. By early 1932, this route was renumbered as Highway 2, and a new highway between Windsor and Leamington via Amherstburg designated as Highway18. Expansion of the highway to four lanes between Windsor and Amherstburg was first proposed in the mid-1960s, but not undertaken until the mid-1980s. In the mid-1990s, the route was determined to no longer be of provincial significance and was transferred—or downloaded—to the municipalities and township that it lay within. On April1, 1997, Highway18 was downloaded through LaSalle, as well between Union and Leamington; it was temporarily rerouted to end at Highway3 in Ruthven. On January1, 1998, the entire route was transferred to Essex County.
