An important milestone has been reached with completion of preliminary design. Over the past four months, the project team has been working hard completing:
- Development of recommended structure alignment
- Geotechnical and environmental soil studies and recommendations
- Site survey and exposure of buried utilities
- Structural modelling of the existing trusses to determine capacity
- Hydraulic modelling of the Red Deer River
- Development of initial applications for project authorizations from Regulatory Authorities
As part of the preliminary design process, a bridge alignment study was completed. Multiple alignments, including an option to maintain the existing alignment, were assessed for risk, cost, and other impacts. The final adopted recommendation is to realign the bridge structure slightly downstream and north of the existing, which best addresses the following:
- Management of risks related to constructability, flooding, and reliance on the existing concrete substructure
- Impacts to the environment
- Impacts to buried and overhead utilities
- Alignment of active transportation corridor
