Vintage postcard of The Saint Claire Tunnel, Port Huron, Michigan, USA.
The Saint Clair Tunnel is the name for two separate rail tunnels which were built under the Saint Clair River between Ontario, Canada and Michigan, USA. The original, opened in 1891 and used until it was replaced by a new larger tunnel in 1995.
It was the first full-size subaqueous tunnel built in North America. (By full-size it is meant that it allowed a railroad to run through it.)
Freight trains used the tunnel initially with the first passenger trains using it in 1892.
Designed by Joseph Hobson the tunnel is a National Historic Landmark of the United States, and has been designated a civil engineering landmark by both US and Canadian engineering bodies. The tunnel measured 6,025 feet (1,836 m) from portal to portal. The actual width of the St. Clair River at this crossing is only 2,290 feet (698 m).
