The first two phases of the ring road, from US 79 on the west side to US 68 on the east side, were constructed in the 1990s. The state decided to complete the orbital road in the 2000s to resolve continuing traffic bottlenecks along US 431 and US 79 on the south side. The second two phases of the beltline were started in 2010 and completed in 2017. Construction of the Russellville Bypass led to a series of route changes over 20 years involving the city's U.S. Highways, special routes, and state-numbered highways.
