The Wilderness trail is a 120km 4 day cycle ride through rain forest and historic gold mining towns on the South Island Westcoast. The Kumara bridge crosses a chasm next to the Taramakau River. Abseil Access won the tender to design, engineer and construct the 75m long suspension bridge across the chasm.
A 1.5m wide deck and 10-person load limit was incorporated make it suitable for large cycle parties and small maintenance vehicles. Engineering review identified the tower footings and ground anchors required 16m3 of concrete. On completion the bridge was successfully load tested to 5000kg.
