Wikipedia:WikiProject U.S. Roads/Missouri/All-time list

Given are the years of the first and last official maps the routes appear on (except for numbers that died in 1926 or 1927, which are starred). These are not always the exact years the routes were created or eliminated (and at least through 1939, since the map is dated January 1, the creation dates are probably the previous year).

In 1929 Missouri designated a "300 mile system" of additional routes, as well as "park connections" and "traffic relief routes". Most suffixed routes were numbered at this time. Unfortunately proposed numbers are not shown, so routes that were renumbered before construction was complete are missing from the table. Missing 1929 numbers: 73 75 109 115
