St. Clair Tunnel (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. 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. 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.) The St. Clair Tunnel Company opened the first tunnel in 1891. The company was a subsidiary of the Grand Trunk Railway (GTR), which used the new route to connect with its subsidiary Grand Trunk Western Railroad (GTWR). Before the tunnel's construction, the GTR was forced to use time-consuming rail ferries to transfer cargo.
