Idaho State Highway 37


State Highway 37 is a state highway in Power County in southern Idaho, United States that spans north-south from the Oneida–Power county line to Interstate 86.

Route description

The SH-37 begins at the Oneida County line on the Rockland Highway, just southwest of Buck Peak. The route heads northwest briefly before turning north to pass through the unincorporated community of Roy. It then continues north through farmland and passes through the town of Rockland before ending at a diamond interchange with I-86, about south of the Snake River, about northeast of Neeley, and about southwest of American Falls.

History

By 1927 the SH-37 designation had been assigned to a route south east of Coeur d'Alene in the northern part of the state.
Between 1927 and 1937, the SH-37 designation was assigned to the highway which had been, by 1927, designated as SH-33. This highway followed the current routing of SH-37 from a point southwest of American Falls south through Rockland and on through Roy, but then continued on to Holbrook, and then finally heading east to Malad City. Also between 1927 and 1937, the SH-38 designation had been applied to a highway that began in Roy and headed east and then northeast to Arbon, north to Pauline and then north to Crystal, and on to terminate in at the former routing of US-91 in Portneuf. By 1956, the southern terminus of SH-38 had changed from SH-37 in Roy to SH-37 east of Holbrook Eventually, the routing of SH-38 was changed to its current route, with the roads through Buist, Arbon, and Crystal to Portneuf being entirely removed from the state highway system; as well as the section that was previously part of SH-37 between Holbrook and the Power County-Oneida County line.
