St. Clair Tunnel

The St. Clair Tunnel is the name for two separate rail tunnels which were built under the St. Clair River between Sarnia, Ontario and Port Huron, Michigan. The original, opened in 1891 and used until it was replaced by a new larger tunnel in 1994, was the first full-size subaqueous tunnel built in North America. It is a National Historic Landmark of the United States, and has been designated a civil engineering landmark by both US and Canadian engineering bodies.
