Sue Higgins Bridge Abutment Protection and Bioengineering
Spanning Calgary’s Bow River, the Sue Higgins Bridge is perched above a wide floodplain. During the June 2013 flood event of intense overland flow, the bridge suffered significant erosion and damage—the intense river hydraulics at the bridge caused the complete erosion of both abutments and rendered the bridge unusable. To restore the bridge, our team designed repairs and future flood protection.
Our hydrotechnical engineers and landscape architects worked together to develop an abutment protection design solution, providing necessary engineering protection to the infrastructure while incorporating native vegetation and landscape design features. Throughout the entire project, we focused on maintaining existing site conditions including fish habitat and mature trees within the project area.
The design included joint-planted vegetated riprap and consideration for fish habitat between the abutments and the river. We placed additional willows within the keyed-in riprap area to promote revegetation of the area. Additionally, we incorporated a layer of hidden riprap within the embankment and pathway approaching the abutments that activate during a flood event. Construction of the project included working within the watercourse, achieving fish isolation, sediment release, and fish salvaging.
