 U.S. Route 19 was added from Abingdon northwest to Hansonville in the late 1920s.Thus, SR 110 was split in the 1933 renumbering; the short piece northwest of Hansonville became part of State Route 71 (which mainly replaced State Route 107).The piece south of Abingdon became State Route 77, and, later that year, the final 0.14 miles (0.23 km) to the Tennessee state line were added.
