You can also see an Imperial Oil Limited gas station in the foreground on the right. Off in the distance, you can see that the cars seem to be backed up on the bridge behind the streetcar. That's the Falls View Bridge - the third one. The first Falls View Bridge was built in 1869 with a bridge deck that was only ten feet wide. It was widened in 1888, to allow traffic in both directions, but it didn't matter for long because a year after the renovation there was a powerful storm that destroyed the bridge. It still lies submerged in the water.
The second Falls View Bridge was built immediately and finished within 117 days after the destruction of the first one. It didn't last long either, because it was unable to carry the weight of streetcars, which were now considered essential. The bridge shown above, also known as the Upper Steel Arch Bridge, was built in 1898. Unfortunately, disaster struck again in 1938, when the bridge collapsed due to ice jams.
