Rainbow Arch Bridge was constructed in 1923 over the Brush Creek.
West of Riverton on the way to Baxter Springs, Kansas you'll find this historic Marsh Arch "Rainbow Bridge" on the old alignment of Route 66. Through the efforts of the Kansas Historic Route 66 Association this historic bridge was saved and restored in 1992. Not only does this bridge make great photo opportunities, but you can still drive over it!
It is the only remaining Marsh Rainbow Arch Bridge on Route 66.
It was listed on the National Registry, March 10,1983.
