This is the inset map for Trenton from the 1959 official state highway map. Numbered routes shown on this map are US 65 and Missouri 6 (in red); and Business Route 65 (in dark blue where it was not concurrent with Missouri 6).

There is a mistake on this map: Tinsman Avenue is shown southwest of the turn on Missouri 6 by the post office. However, that street was (and is) Main Street. The street grid in downtown Trenton is at a 45-degree angle from the street grid in the rest of the city. Ninth and Main is still the major intersection in downtown Trenton. This error was also made in the 1958 inset map of Trenton.
