The Stewart Tunnel was named after James Stewart of Lancashire, Pennsylvania, who was apparently a contractor on the project. It appears that James was thrown from a buggy and killed while he was following the proposed route of the new railroad. As a result of this unfortunate accident the tunnel was named after him.

The tunnel itself is about 1,000 feet in length and is on a curve which means that you cannot see the other end when you initially enter it. The Illinois Central Railroad ran its first train through in February of 1888 and the railroad itself was abandoned in the late 1990's. The lining of the tunnel has been modified numerous times over the years. It now is used by pedestrians and bicyclists on the Badger State Trail.
