Macleod Trail / 162 Avenue S Interchange

Design plans Temporary Interchange How DDI operates FAQ document


Construction update – April 13, 2017

As construction of the new interchange overpass at Macleod Trail and 162 Avenue continues, work is also taking place to upgrade the intersection at Shawville Blvd. and 162 Avenue. View planned Shawville Boulevard upgrades

The upgrades include widening the roadway to accommodate dual-left turns, improving traffic flow and increasing the efficiency of the intersection for pedestrians, transit users and motorists. Crews are also revitalizing the pedestrian connectivity at the intersection to provide better accessibility to the pathways that cross the overpass.

During the rest of April and into May, the closures and restrictions include:

  • intermittent driveway closures
  • full driveway closures with alternate driveway accesses
  • closures of sections of sidewalks and road islands
  • temporary closures and relocations of Transit bus stops.

With the expected congestion drivers may want to consider taking an alternate route.

Crews are also preparing for the upcoming concrete pour of the north side bridge deck. View existing road conditions. A major milestone was reached when the concrete girders for the north bridge of the overpass were installed above Macleod Trail at 162 Avenue early in 2017.

Two-way east-west traffic and pedestrian and cyclist access is being maintained on the current 162 Ave. bridge over Macleod Trail between Shawville Blvd. and Sunpark Dr.

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.

Project timeline

Impacts

Over the next few months the intersection at Shawville Blvd. and 162 Avenue will be the site of construction work as part of improving traffic flow at the intersection. With the expected congestion drivers may want to consider taking an alternate route.

The upgrades include widening the roadway to accommodate dual-left turns, improving traffic flow and increasing the efficiency of the intersection for pedestrians, transit users and motorists. Crews are also revitalizing the pedestrian connectivity at the intersection to provide better accessibility to the pathways that cross the overpass.

During the rest of April and into May, the closures and restrictions include:

  • intermittent driveway closures
  • full driveway closures with alternate driveway accesses
  • closures of sections of sidewalks and road islands
  • temporary closures and relocations of Transit bus stops.

Communications

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