KDOT says a railroad crossing safety improvement project will close K-55 at Belle Plaine for up to five days starting Oct. 4. The project involves installing a non-traversable median at the crossing on the west side of Belle Plaine, in Sumner County. During the work, K-55 will be closed at the crossing. So motorists will have to use other routes, including open portions of K-55 as well as K-15, K-53 and U.S. 81. The closing will begin Oct. 4 and continue as late as Oct. 8. The new median will be designed to prevent someone from driving around crossing bars at the crossing. The modification will allow trains not to blow their horns as they approach the crossing.
