U.S. Route 400 is a mostly east–west U.S. Highway, commissioned in 1994. The highway's eastern terminus is southwest of Joplin, Missouri, near Loma Linda, at an intersection with Interstate 44, which it shares with U.S. Route 166. It originally ended in Garden City, Kansas; in 1996 it was extended to its current western terminus in Granada, Colorado at an intersection with U.S. Route 385.
