West 17 Avenue and 37 Street Main Streets construction

Project update - April 2021

We are preparing for a spring 2021 construction kick-off for the West 17 Avenue and 37 Street Main Street projects. Work on 37 Street S.W. will start the week of April 12. We expect to start work on 17 Avenue S.W. the week of April 19 or April 26.

Construction Impacts & Schedule

We anticipate that each block will take about eight weeks to complete; however, the schedule is subject to change depending on factors such as complexity, weather, and access. Construction will continue until snow and cold weather limit work, typically middle to late October, depending on the year.

Construction is variable. Although we do our best to plan accordingly to reduce the impacts on residents, construction in an older community like this means that sometimes we run into surprises during construction. We don't anticipate any issues, but the timeline could be impacted should we discover any surprises.

We appreciate your patience while crews are working in the area. We know that construction impacts can be disruptive, and we will work to mitigate impacts as best that we can.

As with all City infrastructure projects, we are working to make Calgary a great place to making a living and make a life. Our focus and priority are on completing the project in a timely and fiscally responsible fashion. We know that seeing the work in front of your property can be worrying, and we will work to provide you with timely information to help ease the uncertainty of construction. For ongoing updates, you can sign-up for our electronic newsletter.

What you can expect during construction:

When construction is underway, here's what you can expect:

  • An increase in on-site construction activity, including construction crews, vehicles and heavy equipment. Including an increase in noise and vibration throughout construction.
  • Sidewalk closures and detours will ensure pedestrians and cyclists can travel safely through the area and still access their destinations.
  • The temporary removal of some parking, road closures and potential road detours. Two-way traffic will be maintained during construction, except for occasional closures with a detour. We try to keep closures to long weekends to minimize commute impacts.
  • We don't expect to see large-scale or complete utility shut-downs throughout the replacement of water and sewer lines; however, you will be notified if the need arises due to unforeseen conditions.
  • An increase in truck and equipment traffic accessing the construction sites and surrounding areas, material removal and delivery, as well as on-site flaggers to help direct traffic.
  • Temporary transit stop relocations and detours.
  • Potential construction activity on weekends, weekdays, and overnight as required

Please note, construction in an older community like this means that sometimes we run into surprises during construction. We don't anticipate any issues, but the timeline could be impacted should we discover any surprises. 

We appreciate your patience while crews are working in the area. We know that construction impacts can be disruptive, and we will work to mitigate impacts as best that we can.

Tree Removal

The City of Calgary works to preserve as many trees as possible throughout construction; however, we know that some trees in the existing boulevard on the west side of 37 Street S.W. between 19 Ave and 26 Ave S.W. will be removed.

We are working with our contractors to preserve as many trees as possible throughout construction. Trees provide many environmental, public health and social benefits, particularly in highly developed areas. Removing a tree is a last resort. We have developed a tree protection and compensation plan to protect as many existing trees as possible and replace trees that have to be removed due to construction to replace the lost canopy.

Starting in March, construction crews will be on-site to tag and remove approximately 12 or fewer trees on the west side of 37 Street between 19 Avenue and Richmond Road prior to construction starting. Many of these trees are in poor condition, and once construction is complete, approximately 300 new boulevard trees will be replanted along 37 Street S.W.

Project scope


The City has developed streetscape master plans for 37 Street S.W. and 17 Avenue S.W. based on citizen and stakeholder feedback, technical analysis, and financial considerations. The plans support the needs identified by the community and provides a vision that guides the detailed design and construction phases.

The final design for the 17 Avenue Main Street projects includes:

  • Curb extensions and signal upgrades to improve pedestrian crossings.
  • Sidewalk improvements.
  • Enhanced landscaping; including increasing the urban tree canopy.
  • Wider sidewalks on both sides of the bridge over Crowchild Trail at 17 Avenue.
  • Water and sanitary main upgrades on 17 Avenue between 28 Street and 26 Street, and on 26 Street between 17 Avenue and Bow Trail
  • Utility upgrades.
  • Curb extensions at four intersection near the Alexander Ferguson School as part of the Community Mobility Initiative program.

The final design for the 37 Street Main Street projects includes:

  • We are narrowing the road to slow traffic and create a boulevard, which provides more separation for pedestrians from traffic; this also moves traffic further away from homes that front 37 Street and allows more space for street trees. The additional space allows for approximately 300 new trees planted on 37 Street S.W.
  • The narrow parking lane that exists along most of 37 Street on both sides is being removed, and a road resurfacing will take place between Bow Trail and Richmond Road SW. Once construction is complete, parking will be reinstated in the curb lane with weekday restrictions.
  • The lanes on 37 Street are a mix of lane widths right now, and will be a consistent 3.3m wide once construction is completed.
  • Enhanced pedestrian crossings across side streets will be built through curb extension and the sidewalk on the west side will be wider and separated from traffic by a green boulevard.
  • A multi-use path will be installed on the east side of 37 Street to support a variety of users and separate speeds.
  • New parking restrictions will be enforced on 37 Street. Parking will be restricted, Monday to Friday, between 7 and 9 a.m. and between 3 and 6 p.m. There will be no parking restrictions along 37 Street S.W. on weekends.  

What will 17 Avenue & 37 Street look like?


Project background


37 Street SW (Bow Trail-Richmond) and 17 Avenue S.W. (Crowchild Trail-37 Street), underwent the “design” step of the Main Streets program in 2018 and 2019. The City developed a streetscape master plan for both 17 Avenue S.W. and 37 Street S.W. based on citizen and stakeholder feedback, technical analysis, and financial considerations. The plans support the needs identified by the community and provides a vision that guides the detailed design and construction phases. This vision encompasses numerous considerations, including:

  • Enhanced pedestrian safety and comfort.
  • Improved mobility options, including transit and cycling.
  • A design that reflects its identity of the surrounding communities.
  • Green, friendly streets through naturalized boulevards, trees, and site furnishings.
  • Making 37 Street and 17 Avenue S.W. a destination that will support existing and new local businesses.
  • Improved connections to park spaces and amenities.

Main Streets


The Main Streets Program is one of the ways that the City of Calgary is working to make our city “a great place to make a living, and a great place to make a life.” Our program shares The City’s common purpose of “making life better every day” by implementing a comprehensive process to transform our main streets into places where people want to live, work and play.

To reach their full potential, Calgary’s Main Streets need both public and private investment. The Main Streets program is a continuum that goes from changes to land use that will support development opportunities to a streetscape master plan that is designed to support these changes and can be constructed in a coordinated fashion. The increase in development activity will bring more people and new jobs to the community, making the area more attractive to local businesses and residents.

Core principles


Main Streets are resilient, adaptable, and attractive places that:

  • Celebrate the character of the community.
  • Encourage diversity of businesses, buildings and residents.
  • Create a vibrant destination.
  • Improve public health.
