The Creamery Bridge which spans the Marais des Cygnes River at Eighth Street is one of two Marsh Arch triple span bridges located at Osawatomie. The other spans the Pottawatomie Creek, and both are listed on the National Register of Historic Places.
James B. Marsh patented design used rainbow arches that would expand and contract along with the bridge floor under varying conditions of moisture and temperature. The Creamery Bridge, built in 1930, has a rainbow span reaching 140 feet into the air at its highest point. This is one of only eight Marsh Arch triple span bridges remaining in Kansas.
