	K-141 begins at a southern terminus with K-4 west of the town Marquette. From there, the highway heads north for about before turning north-northwest. After the turn, K-141 travels along the top of Kanopolis Dam. Immediately after crossing the dam, the highway turns northwest, travels a short distance, then gently curves back to a northerly direction. K-141 continues traveling in a northward direction until it is south of K-140, at which time it turns northeast, crosses railroad tracks, then turns back north to its northern terminus with K-140 northeast of the unincorporated community of Carneiro.
