Ontario Highway 11B (Matheson) History - The King's Highways of Ontario

The Matheson-Porquis Junction Business Route was created in 1958, when a new Highway 11 diversion was completed which bypassed a section of the original highway. The old alignment of Highway 11 through Matheson, Monteith, Val Gagne and Porquis Junction was renumbered as Highway 11B. The route was nearly 33 km in length, making it the longest "B" route to exist in Ontario. The route of Highway 11B ran concurrently with Highway 101 through Matheson along Fourth Avenue. Highway 11B also shared a short concurrent route with Highway 67 at Porquis Junction, where the route of Highway 11B finally returned to Highway 11. The route of Highway 11B from Matheson to Porquis Junction was re-designated as Secondary Highway 626 in May 1961. The route remained in the provincial highway system until 1974, when the entire route of Highway 626 was transferred to municipal road authorities.
