Route description
The SH 37 begins at the Oneida County line on the Rockland Highway, just southwest of Buck Peak. (From the southern terminus of SH 37 the Rockland Highway continues south to Holbrook and the western terminus of SH 38.) The route heads northwest briefly before turning north to pass through the unicorporated 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 (Exit 36), about 1 mile (1.6 km) south of the Snake River, about 2.3 miles (3.7 km) northeast of Neeley, and about 6 miles (9.7 km) 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. (By 1927 the north-south route through Malad City was designated as SH 21, but by 1937 it had been changed to SH 36.)
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 (on what was then US-30N, but now I-86) south through Rockland and on through Roy, but then continued on to Holbrook, and then finally heading east to Malad City (on what is now SH 38). Also between 1927 and 1937, the SH 38 designation had been applied to a highway (which, by 1927, had been previously designated as SH 32) that began in Roy and headed east and then northeast to Arbon, north to Pauline (along what is now the Arbon Highway) and then (along what is now the Bannock Highway) 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 (via Buist to Arbon) 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.
