Fish Creek Provincial Park Flood Damage Restoration Bridge Reconstruction

Completion: April 2008

Location: Calgary, Alberta

Owner: Alberta Community Development

As a result the heavy rains and floods in Alberta in June 2005, half of the park's 110km of trails were washed away, and the other half was damaged or required extensive clean-up. The floods also destroyed seven pedestrian bridges over the Fish Creek and seven others were rendered unsafe.

Since the flooding of 2005, Fish Creek Provincial Park has engaged in an extensive reconstruction plan and Trevcon Enterprises Ltd. was proud to work with the Park to reconstruct four of the bridges that were destroyed during the flooding. Bridges reconstructed included bridges 4 and 5 at 30m in length and bridges 6 and 7 at 40m in length.

Because work was being conducted in a protected area, Trevcon worked closely with regulatory agencies such as Department of Fisheries and Oceans, Alberta Transportation, and Alberta Environment to follow the necessary environmental guidelines. Work completed as part of this project included:

  • Site work - grading, excavation, and backfill
  • Removal and disposal of existing substructures
  • Cast-in-place concrete for abutment construction
  • Design, supply, and installation of soil/rock anchors
  • Supply and installation of precast bridge deck panels
  • Post tendioning of bridge structures
  • Bridge deck waterproofing
  • Supply and installation of bridge hand rails
  • Supply and placement of heavy rock rip rap and biotechnical erosion control
  • Landscaping, planting, restoration and pathway paving

In order to complete the entire project, Trevcon sub-contracted Beck Drilling and Environmental Services Ltd. to supply and install the rock anchors. The bridge precast panels were supplied by Lockwood Brothers Concrete Products.
