Bridge Documentation

This is one of only a few examples in Canada of a very rare European style truss bridge with arched overhead bracing and low level top chords. They appear to have been built in limited numbers in Canada by Canadian Pacific with a couple other examples found in western Canada.

A 1950 construction date has been reported for this bridge which seems fairly late for such an unusual bridge design. However this date does coincide with the construction of the power dam upstream. It is possible that the spans were relocated to this site from another location.
