This is the inset map for Charleston from the 1959 official state highway map. Numbered routes shown on this map were US 60 and US 62, both concurrent all the way through Charleston; and Missouri 77 (all numbered routes are shown in red).

Missouri 77 replaced the route of Missouri 55 shown on the 1958 inset map. To avoid duplicating the same number for Interstate 55, about to be built, Missouri 55 was assigned other route numbers.
