History

The US Port of Entry was established in 1836, when a license to provide commercial ferry service between Port Huron and what then was known as Port Sarnia. The license was issued to a Canadian man named Crampton who operated a sailboat. In the 1840s, a man named Davenport, also from Port Sarnia, operated a pony-powered vessel. Steam-powered vessels and paddle-wheelers soon followed, but the first vessel capable of carrying automobiles didn't arrive until 1921.
The Blue Water Bridge was completed in October, 1938, and the ferry operations ceased less than a year later. New passenger-only ferry service ran from 1946 to 1957. A second, parallel span of the bridge was completed in 1997.
