History

When this designation was formed in 1933, the route ran from SR-2, now Interstate 80, in Coalville to the Wyoming border via Pine View. This route was deleted in 1969. The current route of SR-133 was formed in the same year the old route was deleted, 1969. When it was first formed, it made a partial loop around SR-1 (I-15). In 1975 the portion of the highway from the southern terminus of I-15 to the southern Kanosh city limits was deleted, forming the current route.
