The Entrance
Description: This 1837 m tunnel, with a bore of 6 m, linked the Canadian mainline of the Grand Trunk Railway with Chicago via Port Huron, Michigan. It was designed by Joseph Hobson, a Canadian engineer, who also supervised its construction. Tunnelling commenced from both ends in 1888 and on August 30, 1890, the two tunnels met. Train service began on September 19, 1891. Electrification of the line through the tunnel was completed in 1908 and remained until the introduction of diesel trains. With the construction of the adjacent Paul M. Tellier Tunnel in 1993-94, the original tunnel was sealed.
