The Seaway International Bridge first opened in 1962. According to Morrison Hershfield’s Robert Goulet, the bridge “had reached pretty well the end of its service life. When they looked at options of doing rehabilitation or building new, it made more sense to build new.”
The most challenging part of the demolition – seen above in time-lapse – was the arch span in the centre of the bridge because of its height and the fact that it’s over water. It took an estimated four weeks to prep this portion of the bridge for demolition.
