Interstate 215 (I-215), also known locally as the belt route or two-fifteen, is an auxiliary interstate in the U.S. state of Utah that forms a 270-degree loop around Salt Lake City and many of its suburbs. The route begins at the mouth of Parley`s Canyon at the junction of I-80 and heads south through the edge of the Salt Lake City metropolitan area`s eastern suburbs of East Millcreek, Holladay, and Cottonwood Heights. It continues west through Murray before turning north again, passing through the city`s first-ring western suburbs of Taylorsville and West Valley City. It then enters North Salt Lake and Davis County for a short distance before defaulting onto I-15.
