The Fourth Street Trail is broken into two segments; both traverse the west side of Fourth Street. As of late 2011, there is no crossing over I-40. The northern segment runs between US 89 (Historic Route 66) and Huntington Drive, while the southern segment runs between Sparrow Avenue and a side street leading to the Forest Springs neighborhood just north of Butler Avenue. The Fourth Street Trail links with the Route 66 Trail
near the Aquaplex.
Access the Fourth Street Trail from the Forest Spring neighborhood, the Aquaplex on E. Industrial Drive or the Route 66 Trail.
