Ontario Highway 123

The Canadian province of Ontario has an extensive network of Primary (King's), Secondary, and Tertiary Highways, with county-level and city-level roads linking between them. Over the years, however, Ontario has turned back numerous highways to municipal government bodies, renumbered them, or upgraded them to 400-series highways.

In 1997 and 1998, many sections of the provincial highway network were downloaded to local municipalities (such as cities, counties or regional municipalities) by the Ontario Ministry of Transportation as a cost-saving measure. While highways were occasionally transferred to local governments in the past, the 1997–1998 downloads represented the most significant changes to Ontario's highway network. Many highways were completely devolved, while of others only short sections remain under provincial jurisdiction ( Highway 2, once stretching across Southern Ontario, now is only a few kilometres long). Below is a partial list of partially or wholly devolved highways since 1997.

Recycling

Highway numbers have even been "recycled" (used more than once on a provincial highway), however the use tends to be as far as possible from the original routing, and generally a few decades' time separate each numbering, to minimize confusion.

King's Highways
* Ontario Highway 77
* Ontario Highway 102 – Was originally assigned to Canada's first divided highway, now known as Cootes Drive. It bypassed western Hamilton, from McMaster University to Dundas. Now assigned to the Dawson Road bypass of Thunder Bay.
* Ontario Highway 109 – Formerly Eglinton Avenue East, Scarborough. Reassigned to a highway in Cardiff, Ontario which has now been renumbered.

Secondary highways
* Ontario Highway 502 – Formerly the Belleville Road between Marysville, Hastings County, Ontario and Napanee, bypassing the Ontario Highway 2 segment through Deseronto, Ontario. Reassigned and currently in use in Northern Ontario.
