I’m not sure if a ‘reply’ and a’comment’ are separate here so I’m repeating my comment.
Left out is a remarkable feature of the longest bridge in the largest city in Canada, the Prince Edward Viaduct, spanning the Don River Valley and connecting the former towns of Toronto and East York. What is noteworthey is that when the city fathers embarked on this project, someone had the foresight to make provisions for adding a railway track under the roadway and, as a result, the supporting pillars were constructed in the 1920s [unsure of exact date] with a large opening just below their top. Decades later, when Toronto decided to build its second subway in an east-west direction, millions of dollars were saved since the subway tracks were simply constructed using the spaces provided. The Don River below it is also crossed about a kilometre to the south. That bridge is a now unused but well preserved rather unique covered bridge being constructed of cement rather than wood as was the practice at that time. Interestingly it would never have been built if the decision to construct it had been made either one year earlier or one year later. Earlier, the practicability of using cement for a bridge was not yet accepted and by a year later the wheel had so much replaced the sleigh runner in winter transport that the need to cover bridges had passed. Bridges were covered to allow snow to be kept on the road surface of bridges in the winter. It was carted in from the approaches since, without a roof, snow melted under even rthe winter sun, especially since their was no ground frost to keep the surface cold.
