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

Design PlansProject renderingsTCH Sarcee Trail Project​​​​


Construction update – June 13, 2017

Construction crews are currently in the process of paving the transition sections of the TransCanada Highway. This is resulting in traffic delays eastbound because only one lane is open. This situation will likely remain this way until approximately the end of June.

We appreciate the patience and understanding of motorists as the project moves closer to completion.

June 1 marked an important milestone in the staged approach by construction crews in completing the various components of the new TCH roadway and overpass.

Calgarians are now able to 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. Both westbound and eastbound motorists now have access into COP or onto Bowfort Road by using the new overpass.

On the Highway itself, eastbound traffic continues to use the new roadway while westbound traffic remains on the temporary detour road.

The project is anticipated to be fully complete later this summer, but until that time, there will be lane reductions and detours in order to finish the tie-ins from the existing portions of the highway to the newly constructed roadway.

On Bowfort Road lane restrictions and detours related to the partially completed roundabout remain in effect until the work on that roadway is complete.

Speed remains at 50 kms / hour throughout the entire construction zone.

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 timeline

Project background

The Trans Canada Highway (TCH) 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 (COP), a major recreational area and tourist site to the south, and businesses and communities to the north.

An interchange at the TCH and Bowfort Road has been considered by The City since the early 1980’s. The at-grade intersection was the last remaining traffic signal on this section of the TCH, and its removal has been a strategic priority by The City.

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 consistent with current engineering standards. The improved surfaces will provide for enhanced traffic flows and increased safety for vehicles, cyclists and pedestrians.

Lane restrictions and detours related to the partially completed roundabout on Bowfort Road will remain in effect throughout the winter. Motorists are advised to drive with caution on Bowfort Road.

Pathways

The pathway and sidewalk system for use by pedestrians and cyclists will be greatly improved as a result of this project. Some adjustment to the pathway system is needed during construction of this project.

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 followed by a public information session in April.

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 TCH roadway and overpass. As of June 1, Calgarians are able to 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.

During the next few weeks, there will continue to be lane reductions and detours in order to finish the tie-ins from the existing portions of the highway to the newly constructed roadway. Crews are currently in the process of paving the transition sections of the TCH. This is resulting in traffic delays eastbound because only one lane is open. This situation will likely remain this way until approximately mid-June.

On Bowfort Road, lane restrictions and detours related to the partially completed roundabout remain in effect until the work on that roadway is complete.

Speed remains at 50 kms/hour throughout the entire construction zone.
