The Murphy Trail and Bridge in Utah, USA, were used to move livestock from winter range along the Green River to highland summer range from about 1917 to about 1964. The trail and bridge are located in what is now Canyonlands National Park and the trail is now used as a hiking path. The bridge was made from logs and rough-cut planking, and was built around 1917 by J. Idiart and D. Allies. The 10-foot-long (3.0 m) bridge was reconstructed in 1998 and no longer retains historic integrity.
