This awesome bridge reminds me of some of the massive truss bridges in Pennsylvania! I learned about this bridge after sending a letter to Lambton County Public Works asking about truss bridges. The connections are riveted, and would lead me to believe that this bridge was built in the late thirties. However, Lambton County gave a date of 1957 for this bridge. I guess Ontario realized that truss bridges were better than ugly beam bridges, and continued with truss construction longer than Michigan. The bridge does not have v-lacing on vertical and diagonal members, which is characteristic of a newer truss bridge. The top chord has v-lacing on the underside, however, and some of the sway bracing, and portal bracing is v-laced. This road used to be under the jurisdiction of the province, and was Kings Highway 79. A provincial downloading transferred the road, as well as this bridge to the county. The road is now signed as Lambton County 79.
I approached this bridge from the South, and the experience was one of those exciting events since the bridge pops into view suddenly as you round a large curve.

The bridge crosses the Sydenham River, and there is a nice place to stop and see the river on the south side if the bridge.
