Long Description:

This plaque recognizes construction between 1889 and 1891 of the St Clair River Railroad Tunnel. The tunnel was completed at 11.30pm on August 30th 1890.

An engineering feat at the time, two 21 foot shields were used to excavate the tunnel. The total length is 11,725 feet, with 2,290 feet underwater. The tunnel operations were electrified in 1908 and completely dieselized in 1958. Tracks were lowered in 1949 to accommodate larger freight cars. The bore diameter of 19’ 10” could not handle larger freight cars and a new tunnel, 27’ 6” in diameter was opened in 1994.

A corresponding Ontario Historic Plaque marks the Canadian portal of the tunnel.
