U.S. Route 24 (US-24) in the state of Kansas runs east–west across the northern half of the state for 435.95 miles (701.59 km). The route mostly connects rural communities across the High Plains of Kansas, while also later providing an interstate alternate between Topeka, Lawrence, and Kansas City. US 24 both enters and exits the state running concurrently with Interstate 70 (I-70). Along with US 40, the road has largely been replaced by the more modern Interstate in its functionality as a long-distance route.
