You won't see at least one of these signs any more. Missouri 13 was rerouted in November 2002 and replaced by Missouri 413, including the 20-mile or so stretch of its concurrence with US 60 southwest of Springfield. Missouri 14 intersects with these routes in Billings. The redesignation to Missouri 413 meant that there was one less location in Missouri where numerically consecutive routes not only intersected, but were also concurrent.
