 One of the tunnels ("Taft") is over 1.6 miles (2.6 km) in length.When completed, the Route of The Hiawatha will stretch from St. Regis, Montana to the very remote Pearson, Idaho, several miles north of Avery, (equidistantly south of Mullan).The other trail is the "Trail of the Coeur d'Alenes", completed in 2004.
