Macleod Trail / 162 Avenue S Interchange

Design plansDetour Phase 1How DDI operatesFAQ document


Construction update

Temporary road closure – May 27 & 28

Bridge girders will be installed over Macleod Trail from 9:00 p.m. to 9:00 a.m. on May 27 and 28. The 12 girders are being erected during the overnight hours to take advantage of reduced traffic volumes.

In order to ensure the construction area remains as safe as possible and to allow for the installation of the bridge girders, 162 Avenue / Sun Valley Blvd. will be closed between Shawville Blvd. (west of Macleod Trail) and Sunpark Drive (east of Macleod Trail) from 9:00 p.m. to 9:00 a.m. on May 27 and 28. As part of the temporary closure, City Police will be on location to assist.

Detours will be in place for motorists to access Macleod Trail via the Shawnessy Blvd. / Midlake Blvd. interchange to the north.

Northbound and southbound traffic will be maintained on Macleod Trail, however, there will be lane restrictions and detours to move through the construction site.

Pedestrian access will be retained with Police control at the intersection of Macleod Trail / 162 Avenue, along the north side of 162 Avenue.

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.

Impacts

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

Major detour changes are now in effect as traffic has been shifted to the north side of 162 Avenue and Sun Valley Boulevard. See traffic shift map.

In order to ensure the construction area remains as safe as possible and to allow for the installation of the bridge girders, 162 Avenue / Sun Valley Blvd. will be closed between Shawville Blvd. (west of Macleod Trail) and Sunpark Drive (east of Macleod Trail) from 9:00 p.m. to 9:00 a.m. on May 27 and 28. As part of the temporary closure, City Police will be on location to assist.

Detours will be in place for motorists to access Macleod Trail via the Shawnessy Blvd. / Midlake Blvd. interchange to the north.

Northbound and southbound traffic will be maintained on Macleod Trail, however, there will be lane restrictions and detours to move through the construction site.

Pedestrian access will be retained with Police control at the intersection of Macleod Trail / 162 Avenue, along the north side of 162 Avenue.

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.
