South Project
Old Banff Coach Road S.W. to Highway 8
CONFIRMATORY NOISE STUDY
About the Project
The contract for the South project was awarded to Calgary Safelink Partners in 2019. Both the North and South projects were constructed in a design-build contract structure, which means design and construction services were contracted together to a single entity.
Work completed as part of this project included:
- Five kilometres of six- and eight-lane divided freeway
- Reconstructing approximately one kilometre each of Old Banff Coach Road S.W., Bow Trail S.W. and 17 Avenue S.W. (within the Transportation Utility Corridor)
- Four interchanges
- Old Banff Coach Road S.W.
- Bow Trail S.W.
- 17 Avenue S.W.
- Highway 8
Old Banff Coach Road S.W. and 17 Avenue S.W.
Half Interchanges
Alberta Transportation and Economic Corridors’ highway design standards set out minimum distances between freeway interchanges for accelerating and decelerating. This is related to the ability to safely maintain desired speeds on the freeway while also providing enough space to speed up and merge or slow down and exit. The spacing between 17 Avenue S.W., Bow Trail S.W. and Old Banff Coach Road S.W. does not safely allow for full directional access interchanges at Old Banff Coach Road S.W. and 17 Avenue S.W.
The interchanges at Bow Trail S.W. and the Trans-Canada Highway provide all movements. The half interchanges at Old Banff Coach Road S.W. and 17 Avenue S.W. provide access to and from the north and south respectively. This design allows Stoney Trail to safely function as a freeway as intended, while also providing reasonable access to the adjacent road network and lands.
