The famous Rainbow Bridge, about 2 miles (3 km) west of town, was the site where in the year 2000, musician Brad Paisley performed the song "(Get Your Kicks on) Route 66" for the TLC special "Route 66: Main Street America".

The Eisler Brothers Country Store in Riverton was one of the stops on Pixar's US 66 research trips for the 2006 film Cars. The filmmakers met with Dean Walker, then president of the Kansas Route 66 Association, who is known to twist his feet backwards 180° and walk in reverse. He became one of many inspirations for the Mater character, a rusty old tow truck who teaches NASCAR rookie Lightning McQueen to drive in reverse.

The original boom truck is currently based at a restored Kan-O-Tex Service Station in nearby Galena.

The community is served by Riverton USD 404 public school district.
