Eau Claire Area Improvements construction and detours

Construction Update

Anticipated Schedule:

Please note: the schedule is subject to change depending on factors such as complexity, weather, supply chain, and access.


  • Work on the Downtown Flood Barrier and Eau Claire Promenade will focus on earth works, structural work, and deep and shallow utilities. 
  • The Eau Claire Plaza will continue with concrete and earth works for site grading. You will also see the framing of the boardwalk and decking finish.
  • The Eau Claire Lumber Company Building will be open and activated as the Eau Claire Neighbourhood Hub.
  • 3 Avenue metrics and evaluation public survey will be open for input through to the Fall 2022.

Community Impacts & Site Safety

  • You can expect to see increased construction traffic and deliveries.
  • To complete the sidewalk and concrete work in the Plaza and Promenade, crew will be in the area doing sand blasting. We do our best to mitigate and control the dust produced but encourage area residents and businesses to close windows and doors to reduce potential exposure to dust.
  • To complete the Flood Barrier connection at 2 Street S.W., the pedestrian bridge will be closed until the Fall of 2022.
  • The pedestrian ramps at Centre Street are underway. The piles for the ramps are in place, and next the teams will connect RiverWalk and the Bow River Pathway to the Centre Street Bridge.

Pathway Closures and Detours:

With the amount of construction in the area, we know that the pathway closures and detours are going to be extensive in the Eau Claire Area. Major detour routes are updated and posted on our website once they are in place.

  • 2 Street Bridge and pathway closure starting June 6, 2022. Work is expected throughout the summer and into the fall of 2022. 
  • NEW: A localized detour near the north end of Eau Claire Plaza where it connects to Jaipur Bridge will be in place while crews complete tie in work. Pathway users will be rerouted west to connect with the promenade and detour there.
  • The 3 Avenue walking and wheeling improvements (detour) between 8 Street S.W. and Center Street is now open. 
  • Construction fencing extends from Jaipur Bridge to Reconciliation Bridge. Please follow the pathway detour and signage are in place.
  • The existing RiverWalk pathway and bike path will remain open from Reconciliation Bridge to 1 Street S.E. with localized detours around the project area and fencing. Please travel carefully as the pathway widths and detours will vary to accommodate construction.
  • A temporary detour on Riverfront Avenue is now in place to support the Bow River pathway closure from 2 Street S.W. to 1 Street S.E. Pathway users are detoured onto the Riverfront Avenue detour while construction is underway.
  • Sien Lok Park will remain open throughout construction. A temporary pathway along the southern edge of Sien Lok Park extends the pedestrian access from Centre Street to 1 Street S.W. and connects to the Riverfront Avenue detour.
  • The lower level of Centre Street will remain closed for the duration of the pathway closures.
  • The Center Street pedestrian ramps on the south side of the Bow River are closed for their replacement. People walking and wheeling in the area will be detoured. Signage is installed to support wayfinding in the area.

Lower Centre Street Bridge upgrades

  • Starting February 28, the lower deck of Centre Street will be closed. There will be no access for drivers, cyclists and pedestrians.
  • Our colleagues in Calgary Roads are doing rehabilitation work on the bridge structure to upgrade the existing railings and install screens above the concrete arches on the underside of the bridge. For more information, visit Lower Centre Street Bridge upgrades.
  • Once complete, the lower deck detour will be reinstalled. Reopening of the detour and bridge deck is dependent on construction access and progress is subject to change.

Getting around Eau Claire

The City of Calgary is looking at the transportation network in and around Eau Claire to understand where people need to go and how we can make it easier, safer, and more accessible for everyone, whether you travel by foot, bike, bus or car.

Eau Claire is already a very walkable neighbourhood, with good connections to top destinations like the shops and restaurants. RiverWalk and its pathway network make it easy to connect to neighbouring communities like East Village, Chinatown, Downtown West, Sunnyside, and Beltline.


The 2022 detour map below shows recommended detours for walking and wheeling in Eau Claire to maintain comfort, access and predictability. All of these detours are open to walking and wheeling, but the icons depict the suggested mode.

In late 2019, it was identified by the Eau Claire Area Improvements Program team that extensive detours would be required during the multi-year flood mitigation, bridge replacement, and public realm improvements in the area.

We learned from our West Eau Claire Park project that constantly changing detours for roadway and pathway users were costly, unsafe and not well received by those travelling in the area. To support Calgarians in navigating the area throughout construction, it was determined that long-term detours would best serve the community.

Creating safe connections

To maintain safe access to the pathways and cycle network within the city, detours will connect people walking and wheeling along the Bow River Pathway from the West Eau Claire area to RiverWalk in Chinatown and East Village, and the downtown cycle track. Signage will be posted through the construction area; please follow the signs.

Maintaining Access to Businesses and the Community

Access to the businesses and residents along Riverfront Avenue is vital to the community. The driving lanes, loading zones and signage will be adjusted to accommodate a multi-use pathway. This detour allows safer access and travel for people walking and wheeling along Riverfront Avenue.

Keeping greenspace access in the Eau Claire Area

Sien Lok Park will remain open throughout construction. A temporary pathway along the southern edge of Sien Lok Park will be constructed to extend the pedestrian access from Centre Street to 1 Street S.W.

Connecting existing infrastructure

The Downtown Flood Barrier east of Centre Street will use and tie into existing infrastructure such as the RiverWalk pathway. Portions of RiverWalk will remain open throughout construction, and signage will be installed to ensure pathway users can safely navigate the area.

Building a dedicated and predictable detour

The walking and wheeling upgrades along 3 Avenue South will be the dedicated detour for the Eau Claire Area Improvements construction.

Managing the construction zone

At The City of Calgary, we pride ourselves on building a great place to live and a great place to make a life. We know that construction can be disruptive and can feel counter to those goals. Our project managers and contractors have extensive experience in this area. They use lessons learned from previous projects to find new, alternative, and better ways to mitigate the direct impact on Calgarians.

The safety and wellbeing of staff, contractors and the community is an utmost priority for The City.

 As a community, we continue to work through the impacts of COVID19. We will continue to monitor and adjust to ensure the safety of those working on the Eau Claire Area Improvement projects.

Enabling works for the project has started, and construction is set to start in spring 2021. It is important you know what to expect. We are committed to keeping business access open throughout construction.

What to expect

The construction work hours for the Eau Claire Area Improvements Program are Monday to Saturday from 7 AM – 7 PM.

We expect some special work such as girder delivery, that will need to be done outside of those regular hours for safe access to the site. Notification of these expectations will be listed here:

  • An increase in on-site construction activity, including construction crews, vehicles and heavy equipment.
  • Pathway and sidewalk closures and detours along the Bow River Pathway Network and surrounding areas 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.
  • Fencing around construction areas and on-site signage.
  • An increase in noise and vibrations throughout construction. For example, demolition, pile driving, motorized equipment, ground compaction and vehicle back-up alarms.
  • Installation of steel sheet piles that will generate ground vibrations in localized areas.
  • Soil disturbance and dust emissions.
  • An increase in truck and equipment traffic accessing the construction site(s) and surrounding areas.
  • Material removal and delivery, as well as on-site flaggers to help direct traffic and pathway users.
  • Temporary utility shut-downs may be required.
  • Temporary transit stop relocations and detours.
  • Construction activity on weekends, weekdays, and overnight as required.
