K-113 is a state highway in northeast Kansas. It runs from K-18 in southern Manhattan to US-24, passing through the western areas of the City. In Manhattan, the highway is named after Seth Child, an early Manhattan pioneer. Most of the highway is four-laned with mixed-access, and serves as a major arterial highway for the western portions of the city. The highway is almost wholly inside the Manhattan city limit, and ends near the Riley County shops along US-24 north of Manhattan.
