This bridge is a most unusual structure, that may be unique in Ontario. Although it was built in 1959, an era of standardized designs and distinguished by a lack of experimentation, this bridge exhibits numerous highly unusual details. First, as a truss over 50 years old and with welded connections, it is unusual in Ontario. However, the design of the truss is what is most odd. The bridge has been classified as a Parker truss, however, for each of the two truss lines, the top chord for the end panels is not polygonal, but instead maintains a parallel position to the bottom chord. With this unusual design and appearance, one might suspect that the truss is a three span continuous structure, however it is a single simple span. The end post is vertical, another unusual aspect. Furthermore, the 30 degree skew of the bridge has apparently led to the other unusual aspect that the truss configuration is not symmetrical. The end panels with a top chord parallel to the bottom chord is three panels at one end of the truss and only two panels at the other end. For the north truss, the three panel parallel section is at the east end of the bridge, while for the south truss, the three panel section is at the west end. The ends of the bridge each have a single concrete t-beam approach span. The approach spans and abutments are not skewed, only the piers and truss are skewed. Finally, it should be noted that the truss span is 162 feet (49.4 meters) which makes it one of the longest pony truss spans to be found.
This bridge's bottom chord was observed to be covered in large amounts of dirt. Dirt traps moisture and leads to rapid deterioration. A simple program of sending a water truck out to wash truss bridges is a simple, low-cost procedure that can go a long way to increasing the service life of truss bridges.
This historic bridge has been demolished. This map is shown for reference purposes only.
