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.
