The Blackfoot Trail over 9^th Avenue S.E. bridge is a 4-lane structure with two southbound and two northbound lanes. This bridge has been identified for a major rehabilitation to address deterioration. This rehabilitation is expected to improve conditions for motorists and those walking and wheeling along 9 Avenue S.E.

To facilitate the inspection of the upper south retaining wall, the “Corridors” artwork was removed in the fall of 2023.

The project benefits include:

• Improving the condition of the bridge and extending its service life by approximately 30 years
• Improve the overall safety and accessibility of the connection along 9 Avenue S.E. under Blackfoot Trail for pedestrians, cyclists, and motorists, including the addition of streetlights to the Canadian Pacific Kansas City (CPKC) railway bridge.
• Replacing the expansion joint to help prevent further deterioration
• General concrete repairs to help prevent future deterioration of the bridge. 
• Improving a critical link in the transportation network to accommodate opportunities for Calgary's continued growth in the coming years
   

Rehabilitation work will include: 

• Sidewalk replacement and repairs under the bridge to improve the pedestrian experience
• Replacement  of the CPKC railway bridge underpass lighting, improving safety for those walking and wheeling under the bridge
• Replacing existing concrete with a stronger, more resistant asphalt
• Replacement of concrete traffic barriers
• Bridge deck and retaining wall repairs

The City will actively monitor the impact(s) on traffic due to construction activities and make every effort to minimize disruptions to commuters by:

• Coordinating work with adjacent projects when possible
• Reviewing and changing traffic signal timing, as appropriate
• Scheduling traffic and pedestrian detours and closures during off-peak hours and on weekends, when possible

The City will maintain pedestrian and wheeling traffic through the area and clearly mark any closures or detours that may be required to facilitate construction.

The City of Calgary takes a proactive approach to protecting and replacing aging assets; as part of the water main replacement program, we will be performing some work on 15 Street at 19 Avenue S.E. to replace the water main.   The project will see new pipes and the installation of several redundancy features which will make maintenance work more efficient while helping to better support the ongoing water needs for this part of Calgary. Early works for the water main replacement include various infrastructure maintenance, hydrovacing activities with possible test water shut offs and geotechnical drilling.  Interested parties will be notified of any work happening in their area in advance of work beginning.  

Hydrovacing and geotechnical drilling are anticipated to begin as early-works for this water main replacement on or around May 9 and run until or about May 16, 2025.  While work is happening, there will be a northbound lane closure from 7 a.m. to 5 p.m., daily.  Traffic will need to alternate in the remaining lane; signs will be posted to help drivers navigate the lane closure.  Before 7 a.m. and after 5 p.m., the lanes will be fully reopened to traffic.  Construction activities are dependent on several factors. Timelines may change due to inclement weather, complexity, supply chain, and/or other unexpected circumstances.
