The inset map for Trenton, from the official 1950 Missouri highway map. The only constant here is the designation of 9th Street as Missouri 6. US 65 is now on an alignment along the east side of the city, with the former US 65 redesignated Business US 65. Much of what's shown here as City Route 65 no longer carries a route designation. Missouri 6 west of 9th now runs southwest along Main Street (in parallel with the street mislabeled here as Tinsman Avenue).
