List of numbered roads in Essex County

Portions of several county roads within the land given to Windsor lost their designation as a result of this exchange.

The 43 numbered routes provide year-round access to the rural areas of the county, with roads within Windsor under a separate authority.

The longest road in Essex County is County Road 20, which stretches 76.0 kilometres (47.2 mi) between Windsor and Leamington via the shoreline of the Detroit River and Lake Erie.

[2][3] As in the rest of Ontario, the provincially maintained highways in Essex County are designated with a shield-shaped sign topped with a crown.
