​Hagwilget Bridge, Bulkley River Canyon, New Hazelton, British Columbia, Canada

​Twenty four years of experience on the Hagwilget Bridge.

​This single lane suspension bridge, with a 140 m (460 ft.) long main span, was opened to traffic in 1932 and was designed by the BC Department of Public Works in Victoria.

By 1987, the trucks crossing over this 60 year old bridge weighed about three to four times the original design load. Hagwilget Bridge was showing signs of distress and needed strengthening and emergency repairs.
