A Tug or Two

Under the Tasman Bridge, Hobart.  In January 1975, this bridge was hit by a ship passing underneath and the bridge was broken in two.  It divided a city. Overnight, ferries were needed to take passengers across to work. The ferry system remained for the duration of the rebuild, but alas no longer run for commuters. They have now built an additional bridge incase something weird ever happens like that again.
