About the project

Mission Bridge is a vital connection for walking, driving or wheeling in the Mission District. The bridge was built in 1886 and was the first bridge spanning the Elbow River; it opened to traffic in 1915, making it one of Calgary’s oldest bridges. This three-lane bridge spans the Elbow River and connects the communities of Roxboro and Rideau to the Mission District. We’re restoring the Mission Bridge so that its life is extended by about 35 years; part of this restoration includes mobility upgrades for pedestrians, cyclists and motorists. The improvements are necessary to ensure the bridge continues to be safe, functional and in good condition for everyone to use. Lighting enhancements, multi-use pathways and traffic signal improvements are some of the improvements this project will bring.

Did you Know: History Moment

Mission Bridge was made of wood and originally built in 1887.  It was a vital connection between an established Catholic Mission which was in the present-day location of the Holy Cross Hospital.  While the original wooden bridge was located a few blocks south of its current location, it only lasted about 10 years before it needed to be replaced.

Mission Bridge History 1

When it was replaced, it was rebuilt using steel trusses.

Mission Bridge was replaced again in 1912! A plan to upgrade three "major bridges" in Calgary meant the bridge was rebuilt yet again, this time as a concrete structure.  This makes it one of the oldest concrete bridges still standing in Alberta today.

Mission Bridge has survived several  floods.  When it was rebuilt in 1915, there was a flood which caused delays and sadly, the death of a worker.  During the 2013 flood, it was fully submerged in water from the Elbow River.

The bridge has a storied history and has served Calgarians for over 135 years by creating a connection over the Elbow River. 

This bridge has served our city and its people well for over a hundred years – and we're extending the life  of Mission Bridge by another 35 years with our rehabilitation project so that this iconic bridge can continue to bring Calgarians across the river in the Mission district.

Scope of work

The rehabilitation work on the bridge structure will include:

  • general concrete repairs
  • construction of a multi-use pathway on the east and west sides of the bridge
  • life-cycling of signals at the north intersection of the bridge
  • redesign of the three traffic lanes and an overall improvement of the connections at the north and south ends of the bridge
  • repairs to the retaining wall and sidewalk located northwest of the bridge following the Elbow River

Benefits

The project benefits include:

  • improving the condition of the bridge and extending its service life by approximately 35 years
  • upgrading overall mobility for pedestrians, cyclists, and motorists
  • enhancing lighting to improve visibility and accessibility
  • promoting use of alternative and active modes of transportation by building multi-use pathways on the east and west sides of the bridge
  • improving traffic signals at the north end of the bridge
  • improving one critical link in the transportation network to accommodate opportunities for Calgary's continued growth in the coming years

Frequently asked questions

Why is the Mission Bridge in need of repair?

A routine inspection identified structural elements of the bridge that require repair to extend the structure’s service-life by approximately 35 years. No major repair work has been done for over 35 years.

Ongoing regular maintenance along with timely major rehabilitations are critical to keeping bridges safe and reliable while minimizing future expenditures and extending the service life of this type of structure. The project should greatly improve one critical link in the Transportation network and accommodate opportunities for Calgary's continued growth in the coming decades. Rehabilitation of bridges also supports good movement and universal access.

Are you removing the sidewalks?

No, we plan to improve sidewalks on the east and west sides of the bridge by building multi-use pathways.

What are the traffic impacts during construction?

  • May 13 through Late Summer 2024: the west lane across the bridge will be closed. The east side of the bridge will be modified to allow one north and one southbound lane.  Cyclists will continue to share the road with motorists while pedestrian access will be maintained on the east side of the bridge.  During this time, access to Elbow Island from the west side of the bridge will not be possible.  
  • Late Summer through Fall 2024: the east side lane will be closed. During this lane reduction, the west side of the bridge will be modified to allow one north and one southbound lane.  As with the Spring/Summer lane reduction, cyclists will continue to share the road with motorists while pedestrian access will be maintained on the west side of the bridge.  
  • Fall 2024 through Spring 2025: the bridge will fully be closed to motor vehicles. Pedestrians and cyclists will still be accommodated, including access to Elbow Island.
  • Spring 2025: the bridge will reopen to two-way traffic with further planned lane reductions.
  • Late 2025: anticipated project completion.

What is going to happen to Elbow Island?

Elbow Island access will be closed over a portion of the summer as work is ongoing.  The west sidewalks of the bridge will be closed during this stage of construction.  Rafters/floaters on the river over the summer months will be redirected to one side of the Elbow River based on the work being done.  Rafters/floaters are asked to follow posted construction signage along the river for their safety and that of construction crews.

Will there still be three traffic lanes for motor vehicles once construction is finished?

Yes, the number of motor vehicle traffic lanes will remain the same (two northbound and one southbound) once construction is completed; although, the width of all lanes will be consistent and improve mobility.

What are you doing about tree removal and replacement for construction work?

We had to remove some trees in preparation of the retaining wall work but we have a plan to restore habitat once construction is complete.

What are some of the benefits of this work once construction is done?

This redesign of Mission Bridge was based on feedback from public engagement done in 2022. Your thoughts and ideas gathered from this process played a big part in the new design which will feature wider sidewalks, improved pathways and connections, uniform traffic lane widths, better bridge aesthetics and lighting upgrades.

What is the project budget?

The project budget is $17.8M.

How can I stay informed while construction is ongoing?

Look for the project team who will be out and about through spring 2024 on pathways by the bridge and in the community. If you see the team, feel free to come over and ask questions. You can also sign up for our project newsletter. Be sure to keep an eye out for our booth at the Lilac Festival on June 2!

Will construction impact street parking?

Due to the nature of work, you may occasionally see project vehicles parked for a short time on the street in a residential area. This is generally rare and not for long periods of time.
