Seymour Canyon Suspension Bridge

The 73 metre suspension bridge consists of a 2.5 metre wide timber deck on steel beams, hanging on steel cables. The Seymour Canyon Suspension Bridge will serve as a replacement for the Twin Bridge, which was removed after a rock slide in the Lower Seymour Conservation Reserve. The structure will be used by pedestrians, cyclists and equestrians using the trail system.

The design of the replacement bridge addressed:

• Challenging terrain and site access, including steep banks and uphill slopes, exposed rock, poor soil conditions and composition, and dense vegetation
• Challenging geotechnical conditions, such as rock buried under a thick layer of soft soil
• Protection of existing infrastructure and utilities at Riverside Drive
• Limited construction access and areas for equipment and material laydown
• Need for additional road and trail construction, and the associated impact to the surrounding mature forest
• Protection of the Seymour River from sedimentation and deleterious substances during construction
• High water and flood events
