Macleod Trail / 162 Avenue S Interchange

Design plans Detour Phase 1 How DDI operates FAQ document


Construction update - June 28, 2016

The City of Calgary has instituted the permanent closure of the temporary right-out access onto Macleod Trail from The Boulevard Shopping Centre (which includes businesses such as the Landmark Cinemas and the Superstore).

The right-in access into the shopping centre from southbound Macleod Trail will remain open.

This closure allows crews to continue moving forward on the building of the interchange at Macleod Trail and 162 Avenue by starting the construction of ramps in the area. This is another step within the construction schedule to ensure that the interchange project remains on-track.

Three lanes of straight-through traffic in each direction continue on Macleod Trail traveling through the intersection. Along with reinstated right turns at the intersection, dedicated left turns off Macleod Trail remain.

Motorists are advised to observe all posted signs and drive with care through the construction zone.

About the project

The interchange at Macleod Trail and 162 Avenue S will be an integral part of The City’s overall transportation network, helping to enhance Macleod Trail as a free-flow gateway to the city from the provincial highway network. Construction of the interchange will enhance mobility for commuters, cyclists and pedestrians while accommodating access to surrounding businesses and services.

After completing an analysis of the traffic flow at the intersection and evaluating several designs, it was determined that the Diverging Diamond Interchange (DDI) was the most appropriate layout for an interchange at that location. This is the first DDI to be constructed in Canada.

This project includes:

  • an interchange at Macleod Trail and 162 Avenue which allows for free-flow traffic north and south on Macleod Trail underneath the interchange bridges
  • two bridges over top Macleod Trail (as part of the interchange) for east and west traffic on 162 Avenue and Sun Valley Boulevard
  • intersection improvements at Shawville Blvd. and 162 Avenue
  • a basketweave structure to accommodate access for southbound traffic onto Shawville Blvd. (south end of area shopping centre)

The project is being coordinated with Provincial plans for the Southwest Calgary Ring Road (SWCRR). The prime consultant for the project is ISL Engineering and Land Services Ltd. and Graham Infrastructure LP is the general contractor.

  • Fall 2016: Begin phase 2 of detour construction
  • Winter 2016 – Fall 2017: Construction of third bridge/overpass structure and associated roadworks
  • Fall 2017: Anticipated completion of project

Impacts

This project has resulted in significant road and pedestrian road restrictions and closures.

The City has instituted the permanent closure of the temporary right-out access onto Macleod Trail from The Boulevard Shopping Centre (which includes businesses such as the Landmark Cinemas and the Superstore).

The right-in access into the shopping centre from southbound Macleod Trail will remain open.

Earlier this spring, right turns were reinstated at the intersection of Macleod Trail and 162 Avenue/Sun Valley Blvd. At the same time, the temporary right turn ramps in use since last year were closed.

Three lanes of straight-through traffic in each direction continue on Macleod Trail traveling through the intersection. Along with the reinstated right turns, dedicated left turns off Macleod Trail remain.

Motorists are advised to observe all posted signs and drive with care through the construction zone.

Communications

Stakeholder communication and engagement has always been an important component of the Macleod Trail/162 Avenue Interchange planning process.

A total of three sets of public information sessions have been held related to this project.

In addition, two special sessions for businesses in-and-around the future interchange took place in April 2015 and March 2016.
