Following several difficult winters, in 1837 Philadelphia City Council authorized the building of the first ice-breaking boat, made for use on the Delaware River. The steam-driven boats could plow through a foot of ice, ensuring access to the Port. They were no longer needed by 1907, as the river ceased freezing.
