Macleod Trail and 162 Avenue South Interchange 

Spring 2017 Project Update 

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. 

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 hat cross the overpass.

From the beginning to the middle of May, the closures and restrictions around the intersection include:

  • Intermittent driveway closures
  • Full driveway closures with alternate driveway accesses
  • Closures of sections of sidewalks and road islands
  • Temporary closures and relocation of Transit bus stops.

The project webpage www.calgary.ca/macleod162ave will be updated on a regular basis with details of the construction impacts.

January 24, 2017 – Project Update

As work continues on the construction of the north bridge structure of the new interchange at Macleod Trail and 162 Avenue, some temporary closures and lane restrictions will take place overnight on Jan. 31 and Feb. 1, 2017. These temporary closures and lane restrictions are necessary to allow construction crews to erect girders for the north bridge structure. These closures will take place overnight from 9 PM to 5 AM.

January 31 Closures

  • Southbound lanes of Macleod Trail closed
  • Both directions of traffic shifted onto northbound lanes of Macleod Trail (2 lanes north; 1 lane south)

February 1 Closures

  • Northbound lanes of Macleod Trail closed
  • Both directions of traffic shifted onto southbound lanes of Macleod Trail (1 lane north; 2 lanes south)
  • Access ramps to northbound Macleod Trail will be closed
  • Traffic to northbound Macleod Trail detoured north from Shawville Blvd./162 Ave. intersection
  • Traffic to northbound Macleod Trail detoured north from Midpark Blvd./Sun Valley Blvd. intersection

Two-way east-west traffic and pedestrian and cyclist access will be maintained during this time on the current 162 Ave. bridge over Macleod Trail between Shawville Blvd. and Sunpark Dr.

Please also note that there will be lane restrictions/closures on Shawville Blvd. south of 162 Ave.  from Jan. 23 – Feb. 5 as ENMAX completes utility work.

About the Project

  • The interchange at Macleod Trail and 162 Avenue South will be an integral part of The City’s overall transportation network that includes commuters, cyclists, pedestrians, transit users and High Occupancy Vehicles (HOV).
  • When complete, motorists will be able to travel on Macleod Trail from Lake Fraser Gate to 194 Avenue without going through any traffic lights.
  • Construction of the interchange and roadway will improve access and connectivity to and from Macleod Trail for the communities of Sundance, Midnapore, Shawnessy, Somerset, Bridlewood as well as Evergreen, and the surrounding businesses and services, including Shawnessy Towne Centre.
  • With the construction activity and utility relocations, this project has resulted in road restrictions and closures. Detours have been established for both local businesses and commuting traffic. Motorists should expect delays when travelling through the construction area.
  • In April 2016, traffic on 162 Avenue and Sun Valley Boulevard will be shifted to the north side of the roadway to allow for construction of new roadways and overpasses on the south side throughout 2016. Impacts include the closure of left turn access from both directions of 162 Avenue onto Shawville Boulevard, closure of Sunpark Gate to the south at Sun Valley Boulevard, the removal of temporary signals on Sun Valley Boulevard, and reopening a single lane left turn from northbound Macleod Trail to westbound 162 Avenue.
  • Construction of the interchange bridge structures is scheduled to continue throughout 2016, with completion of the interchange by the fall of 2017.
  • We continue to keep the project webpage updated on a regular basis at www.Calgary.ca/Macleod162Ave.

 FAQ

What is this project all about?

The City’s Transportation Department is building an interchange at Macleod Trail and 162 Avenue South. This interchange will be an integral part of The City’s overall transportation network that includes commuters, cyclists, pedestrians, transit users and High Occupancy Vehicles (HOV). The interchange will help to enhance Macleod Trail as a gateway to the City from the provincial highway network, and when complete, motorists will be able to travel Macleod Trail from Lake Fraser Gate to 194 Avenue without going through any traffic lights.

Why is the interchange being built now?

City Council has identified the West Macleod area south of Stoney Trail and west of Macleod Trail as a Priority Growth Area for the City. The interchange will help to facilitate this growth, as well as address existing traffic issues, and coordinate this project with the Alberta Government who is responsible for the construction of the Southwest Ring Road (Stoney Trail).

What are some of the benefits of the interchange?

Construction of the interchange and roadway at this location will:

  • Improve mobility for commuters, cyclists and pedestrians while accommodating access to surrounding businesses and services;
  • Improve access and connectivity to and from Macleod Trail for the communities of Sundance, Midnapore, Shawnessy, Somerset, Bridlewood and Evergreen, and Shawnessy Towne Centre;
  • Coordinate with the Alberta Government the planned provincial improvements at Macleod Trail and Stoney Trail (formerly Highway 22X), in conjunction with the Southwest Ring Road; and
  • Increase road capacity to serve priority growth areas in southwest Calgary, including transit-oriented development around area LRT stations.

Will there be impacts to the flow of traffic in the area during construction?

Yes. Construction on this project will result in a number of lane closures and detours. The City will do its best to mitigate these impacts to local businesses and commuting traffic during construction. See below for the construction schedule and 2016 detour plan.

What kind of interchange is being built?

After completing an analysis of the traffic flow at the intersection and evaluating several designs, it was determined that a Diverging Diamond Interchange (DDI) was the most appropriate layout for an interchange at this location. While the Diverging Diamond has been constructed in other parts of the world, this will be the first urban DDI in Canada.

How does the DDI work?

The diverging diamond interchange (DDI) is designed in such a way that the two directions of traffic on 162 Avenue will briefly cross to the opposite side of each other on bridges over Macleod Trail. This allows more effective traffic flow at the signalized intersections within the interchange, and enables left-turning vehicles to proceed without crossing opposing traffic. This design significantly reduces delay and improves efficiency compared to a more traditional diamond interchange.

Check out the videos on the project webpage to see how the interchange will work once it’s completed.

What are the other benefits of the DDI?

Benefits of the DDI include:

  • Consolidation of the pedestrian and cyclist corridor to the centre of the bridge resulting in more convenient pedestrian and cycling travel across the interchange;
  • Less space required for interchange bridges;
  • Increased capacity for turning movements to and from ramps;
  • Free-flow left-turn movements from both directions on 162 Avenue to Macleod Trail northbound and southbound; and
  • Simplified and more efficient traffic signal operations with less delay for traffic.

Who is doing the work?

  • The City of Calgary is leading the project;
  • ISL Engineering is responsible for design and construction administration; and
  • Graham Infrastructure LP is the general contractor.

What is the budget for this project?

The estimated cost for the project is $68 million.

Impacts – Permanent Closure of Shopping Centre Right-Out Access

The City of Calgary is proceeding with 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.
