Ontario Highway 7A (Alt) Ashton-Stittsville History

King's Highway 7A (Alt) was created in 1961, when the Highway 7 designation was added to the existing route of Highway 15 between Carleton Place and Ottawa. The Highway 7A (Alt) designation was applied to a bypassed section of Highway 15 between Ashton and Stittsville, which was known as Highway 15A (Alt). The bypassed 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) after a Highway 15 relocation project was completed in 1956. The concurrent route of Highway 7A (Alt) and Highway 15A (Alt) was decommissioned in 1969, when jurisdiction over the highway was transferred from the province to the municipal tier. Jurisdiction over the easternmost section of the highway from Stittsville southerly to Stanley Corners was transferred from the province to the newly-created Regional Municipality of Ottawa-Carleton, effective January 1, 1969. This section of the highway subsequently became part of Ottawa-Carleton Regional Road 5. The balance of the highway from Stanley Corners westerly to the Highway 7 & Highway 15 Junction at Ashton Station was transferred to the Township of Beckwith and the Township of Goulbourn, effective April 1, 1969.
