King's Highway 99, also known as Highway 99 or The Governor's Road, was a provincially maintained highway in the Canadian province of Ontario that connected Highway 24 north of Brantford with Highway 8 in Dundas, lying approximately midway between Highway 2 to the south and Highway 5. The Governor's Road, an important historical highway that is a part (and an alternate historical name of) Dundas Street, continues west of Highway 24 to Woodstock and onwards to London. Highway 99 was first designated as Highway 5B in 1938, but was renumbered by 1940. The route was paved in 1953, but otherwise remained unchanged until the 1980s, when it was truncated at the Brant County – Hamilton-Wentworth boundary. The remainder of the route was decommissioned in 1997.
