Kan. Stat. § 66-227
It is hereby made the duty of every person or corporation owning or operating any railroad crossed by a public highway, county highway or township road to make, and keep in good repair, good and sufficient crossings for such highway, road or street over their tracks, including all the grading, bridges, ditches and culverts within their right-of-way that may be necessary to make a safe crossing. The vertical profile or alignment of the centerline of the highway, road or street through the crossing shall comply with the American association of state highway and transportation officials (AASHTO) design manual titled, "a policy on geometric design of highways and streets" as published and in effect on January 1, 2001.
When the highway crossing the track is improved by the construction of a hard-surfaced road, the railroad company shall pave the space between the rails and for a distance of two feet on each side thereof with a pavement of the same or a better type for the full width of the pavement on the highway. On other crossings where the highway has not been improved, the planking or other material used between and for a distance of one foot outside of the rails shall be of a length to equal the roadway width measured perpendicular to the axis of the highway. Nothing in this act shall be construed to repeal any provision of law relating to railroad crossings on streets in cities of the first and second class.
