Business 80 then consisted of two connected segments. The western segment ran concurrently signed with U.S. Route 50 (US 50) and also carried the unsigned designation of I-305. The eastern segment was assigned the unsigned designation of State Route 51 (SR 51). After travelers complained that Business 80 was difficult to follow, it was named the "Capital City Freeway" in 1996. As part of a re-signing project which commenced in 2016, references to Business 80 on the western segment are to be removed, subsequently marking the route as only US 50, but as of 2018 little progress has been made.
