摘要：

Edmonton Country Club has a 68.6 m (225 ft) long historic suspension bridge on its premises crossing a 18 to 24 m (60-80 ft) deep ravine. The bridge was constructed about 60 years ago using wooden towers and steel cables and serves pedestrian and golf cart traffic between tees. Varying degrees of decay developed over the years at the base portion of the towers raising a concern about the safety of the structure. Remedial measures were implemented in 1999 to extend the serviceability of the wooden columns in a cost-effective manner and without significantly altering the original appearance of the structure. The decayed areas of the columns were first treated with patented wood preservative materials to arrest the fungal growth. In the second stage, a structural steel retrofit system was built around the lower 3 m (10 ft) height of each of the wooden columns to ensure that the rotted wooden zones would be properly reinforced.
