Trans Canada Highway / Bowfort Road N.W. Interchange Project and related roadworks

Design PlansProject renderingsTCH Sarcee Trail Project​​​​

Construction update – July 18, 2017

Traffic is now flowing both east and west on the new Trans Canada Highway underneath the new overpass at Bowfort Road N.W., however, motorists are reminded that speed remains reduced to 50 km/hr throughout the entire construction zone as some work will continue in various areas until late August.

Beginning July 19, asphalt paving will take place for approximately one week on the Trans Canada Highway westbound lanes and along the Bowfort Road and 83 Street areas. Lane reductions will be in place and motorists should expect traffic delays.

Calgarians can now use the new bridge structure over the TCH roadway to enter Canada Olympic Park (COP) to the south and the Bowfort Road business area to the north. However, construction work continues at the interchange as there are currently only single left turning lanes.

About the project

The project design includes the creation of a free-flow six-lane roadway for 16 Avenue NW/Trans Canada Highway (TCH) beneath a new interchange/bridge at Bowfort Road. The new interchange will have dual left turns in all directions and two through lanes in each direction on Bowfort Road. The project also includes roadway and utility improvements along Bowfort Road, 83 Street N.W. and Canada Olympic Drive.

The ultimate plan is designed to incorporate the future interchange upgrade at Stoney Trail to the west and accommodate a basket weave structure in the eastbound direction. Alberta Transportation has been consulted to ensure coordination with the TCH/Stoney Trail Interchange project. The plan also accommodates the widening of the Trans Canada Highway should that be required in the future.

Project background

The Trans Canada Highway (16 Avenue North) is a major east-west transportation route through Calgary, providing a continuous link through the city and connecting to the provincial and national highway systems. The segment of the highway between the west city limits and Sarcee Trail is the primary entrance to Calgary from British Columbia and the Rocky Mountain Parks.

Bowfort Road is a major road servicing Canada Olympic Park, a major recreational area and tourist site to the south, and businesses and communities to the north.

The previous intersection was not capable of handling the traffic volumes generated by large scale events at Winsport, or the 60,000 vehicles that passed through the area every day. In July 2014 Council approved the plans to move ahead with an interchange at this location.

Bowfort Road / 83 Street N.W.

83 Street and Bowfort Road have been reconstructed with new underground utility services and a new paved road and pathway/sidewalk areas. The improved surfaces will provide for better traffic flows and increased safety for vehicles, cyclists and pedestrians.

Lane restrictions and detours related to the partially completed roundabout on Bowfort Road remain in effect until the work on that roadway is complete. Motorists are advised to drive with caution on Bowfort Road.

Pathways

The pathway and sidewalk system for people walking and cycling will be greatly improved as a result of this project. Some adjustment to the pathway system is needed during construction of this project.

Impacts

With construction activity and utility relocations, this project has resulted in road restrictions, closures and detours, established for both local businesses and commuting traffic. Crews are working on a staged approach to complete the various components of the new roadway and overpass.

Traffic is now flowing both east and west on the new Trans Canada Highway underneath the new overpass at Bowfort Road N.W. Speed remains reduced at 50 kms / hour throughout the entire construction zone as some construction activities continue over the next few weeks. We appreciate the patience and understanding of motorists as the project moves closer to full completion, and ask that all construction signs be followed.

Calgarians can now use the new bridge structure over the TCH roadway to enter Winsport to the south and the Bowfort Road business area to the north. However, construction work continues at the interchange as there are currently only single left turning lanes.

Public Art

There are two elements of public art, designed to capture the essence, personality and history of this location. The four Towers on the south side of the TCH feature unique rundle stones, placed mid-way up where they appear to be ‘floating’. The towers align with the Blackfoot cultural symbolism: four seasons, four directions, four elements, four human stages. The earthworks element of the public art is located on the north side of the TCH and creates a fusion of the past and present, echoing the spirit of place and energy of the land.

Public engagement/communications

Communications and stakeholder and public engagement has occurred regularly in relation to this project.

In May 2014 small group update sessions were held with area businesses and property owners, as well as the Bowness and Valley Ridge Community Associations with a proposed revised design. In June 2014, two public open houses were held to provide the same information.

Further small group stakeholder meetings were held in 2015 to provide more details on the construction of the interchange and associated roadworks. An Information Session for businesses along Bowfort Road was held in March 2015 followed by a public information session in April.
