History of Secondary Highway 502 (#1):
There have been two Secondary Highways in Ontario known as Highway 502, but they have existed at different times. The first route of Secondary Highway 502 was particularly unique when it was first designated in 1956, because it was Ontario's most southerly Secondary Highway. This route ran from Marysville to Napanee in Eastern Ontario. This highway was intended as a short cut-off route so that through traffic could bypass Deseronto. The route of Highway 2 did not offer motorists a particularly direct route between Marysville and Napanee because it turned a fair distance to the south at Marysville. For several years, Highway 502 was a heavily-used alternate route to Highway 2 between the two communities. However, once Highway 401 was completed between Belleville and Napanee, most through traffic was diverted onto the new freeway instead. As a result, Highway 502 quickly declined in importance and was eventually decommissioned as a provincial highway in 1973. This former highway is now known as Lennox & Addington Road 1 and Belleville Road (Formerly Hastings Road 24). Since 1980, the Highway 502 designation has been used to mark another highway which links Fort Frances to Dryden in Northwestern Ontario.
