History

Previous route

When it was first formed in 1933, SR-138 took a similar path to the present-day route, going from Grantsville north to Burmester. This designation was deleted in 1953.

Current route

The current route of SR-138 was formed in 1965, when SR-2 was moved to the north to reflect the future alignment of then under-construction I-80. The state legislature wanted to keep the old alignment of looping down to Grantsville in the state highway system, so it was re-designated as SR-138. This designation has remained the same since that action. In the May 2018 meeting of the
