Alberta Provincial Highway No. 9, commonly referred to as Highway 9, is a highway in south-central Alberta, Canada, which together with Saskatchewan Highway 7 connects Calgary to Saskatoon, Saskatchewan via Drumheller. It is designated as a core route of the National Highway System, forming a portion of an interprovincial corridor. Highway 9 spans approximately from the Trans-Canada Highway (Highway 1) east of Calgary to Alberta's border with Saskatchewan. Route description Highway 9 begins at its interchange with Highway 1 approximately east of Chestermere and west of Strathmore, and approximately north of Langdon via Highway 797. For its first , Highway 9 generally runs in a north/south direction to Beiseker, where it meets Highways 72 and 806. At Beiseker, Highway 9 runs in an east-west direction for to Drumheller, where it meets Highways 10 and 56. Highways 9 and 56 then run in a north/south concurrence for from Drumheller to its intersection with Highway 27 east of Morrin. Highway 9 leaves the concurrence at this point and runs east/west for the balance of route to the Saskatchewan border, providing connections to Hanna and Oyen as well as numerous smaller communities, and generally running parallel to Highway 12 to the north. The highway continues as Saskatchewan Highway 7 in a northeast direction toward Saskatoon. History Over the past few years, the province of Alberta has executed a number of upgrades to the highway, widening shoulders and realigning the road (most recently just west of Drumheller, although the new alignment now bypasses the Horseshoe Canyon landmark as a result). As of 2007, however, the province has yet to twin any stretch of the busy highway, and there have been calls for interchanges to be built at its junctions with Highway 21 and the Trans-Canada due to the number of fatal automobile accidents that have happened at these locations. A partial cloverleaf interchange was constructed in 2007 where Highway 9 crosses the Trans-Canada Highway. As well, the junction with Highway 21 was changed to a four-way stop in early 2011.
