Calgary, AB,

Trans Canada Highway N.W. detour almost complete

The temporary Trans Canada Highway (TCH) detour roadway near Canada Olympic Park is almost complete and traffic will be moved onto the detour starting Wednesday, Sept. 2.

The six-lane detour was built beside the current highway as part of the interchange project at TCH (16 Avenue) and Bowfort Road. The detour will handle traffic for approximately 15 months while the interchange is being constructed. Speed will be limited to 50 kms/hour on the detour.

Access to Bowfort Road north of the TCH will be maintained during this time, while access to Canada Olympic Park will be detoured through a temporary intersection, located 500 metres west of the current intersection.

Prior to the opening of the detour there will be some lane restrictions and closures on the Trans Canada Highway on Aug. 31 and Sept. 1 to allow for the completion of traffic signal work. Calgary Police Service will be on hand to help ease the traffic delays.

Once traffic has been moved onto the detour, excavation can begin on the existing TCH road in preparation for the beginning of bridge construction later this fall and into the winter.

The plan for the new interchange includes the creation of a free flow six-lane roadway for 16 Avenue N.W./TCH beneath a new interchange/bridge at Bowfort Road. The interchange will have dual left turns in all directions and two through lanes in each direction on Bowfort Road.

The City is working towards an anticipated opening of the new interchange in late 2016 with completion of all final construction elements (ex. landscaping) by the summer of 2017.

The new interchange is an important part of a safe, effective transportation network that supports and services the surrounding recreation, business and community network, and the city at large.
