Ontario Highway 15A (Alt) Ashton-Stittsville History

King's Highway 15A (Alt) was created in 1956, when a more direct Highway 15 alignment opened to traffic between Ashton and Stittsville. This relocation of Highway 15 was a Trans-Canada Highway project that was started in 1955. Once the relocation project was completed in late 1956, the original route of Highway 15 through Ashton and Stittsville (via Ashton Station Road, Ormond Road, Flewellyn Road, Huntley Road and Main Street) became Highway 15A (Alt). The route was apparently decommissioned during 1969, since the highway does not appear on Official Ontario Road Maps after 1970. Highway 15A (Alt) ran concurrently with Highway 7A (Alt) for its entire length between 1961 and 1969.
