The 6.2 miles from Mokane to Tebbetts have changed little since the early days of the Katy Railroad. Like Tebbetts and many other towns along the trail, Mokane was established as a railroad town, and its name comes from the Missouri, Kansas and Eastern Railroad, part of the Katy Railroad. In this stretch, the Katy Trail State Park runs in the Missouri River floodplain under the bluffs and as far from the river as possible to avoid floods. The bluffs above the trail are composed of Jefferson City dolomite, a magnesium-rich limestone formed several hundred million years ago when Missouri lay under shallow inland seas. In the fertile floodplain are fields of corn and soybeans. The route crosses two large streams in the Mokane-Tebbetts segment: Middle River by a 1926 steel through-truss bridge and Hiller's Creek by an 1897 pony-truss bridge. Tebbetts, founded in 1892 as a stop on the new line to St. Louis, still shows its railroad past in the open space at the town's center, once the site of the depot and sidetrack.
