I fell down reading about all the ships that have hit bridges, and this is probably the most practical solution for a lot of scenarios.
Yes, but Hobart is tiny so this rarely happens and relatively few people are impacted when it does.
Seems like a fair few people are going to be impacted permanently in Baltimore because of this.
"Permanently" what? the harbor will be cleared, probably sooner than later, and there will be a new bridge/tunnel built in a few years. Like that's not permanent.
