You crash a ship into it.
The bow of the Delta Mariner was covered in twisted steel and chunks of asphalt from the two-lane bridge. The boat hit the bridge Thursday night on the Tennessee River on its way to Cape Canaveral, Fla. .....The five-story high Delta Mariner was too tall to pass through the portion of the bridge that it struck (you don't say), and the resulting collision left a 300-foot wide gap.
Skipper! You got some 'splainin to do!
