A Missouri Supplemental Route is a state secondary road in Missouri , designated with letters. Supplemental Routes were various roads within the state which the Missouri Department Of Transportation were given in 1952 to maintain in addition to the regular state routes. The goal of the secondary highway system was to place state-maintained roads within two miles of more than 95% of all farm houses, schools, churches, cemeteries and stores. The four types of roads designated as supplemental routes are:
Supplemental routes make up 19,064 miles (59%) of the state highway system. HIGHWAY DESIGNATIONS Various letters (but not all) are used in the designations of these highways. The letters "G", "I", "L", "Q", "S", and "X" are not used. With the exception of Route AR south of Bakersfield , the letter "R" is only used as discussed below. Additionally, some routes are double letters (such as Route AA, MM). Usually, but not always, double letter routes are farm to market roads which end at county roads or are former alignments of other highways. Additionally, combinations of letters may be used, but always with "A" as the first letter (such as Route AD). The only exception is Route BA found in western St. Louis County . Supplemental routes which connect with state parks or other recreational facilities begin with the letter "R" (such as Route RB). These routes rarely run for more than a few miles, though they may cross county lines. But at other highway crossings, they usually (but not always) change names. For example: In Greene County , southbound State Route J crosses U.S. Highway 60 and becomes State Route NN. But when State Route MM crosses Missouri State Route 360 , it remains MM, only changing into State Route B when crossing Interstate 44 . The names are also reused, but not near one another. No letter is reused in a county. State Route D exists in Greene County, Newton County, and in several other counties. SIGNAGE Supplemental routes are signed by black letters on a white background with a black border. Occasionally they will be marked with banners such as EAST, WEST, or END, but this is extremely rare. There are no business or bypass routes for the roads, however three examples exist of , Spur Route C in Gentry County , and Spur Route Y in Montgomery County . It is erroneously believed that due to these roads being designated by letters rather than numbers and their existing in more than one county that these roads are county roads, not state highways, with some businesses and residences located on these roads saying their address is "County Road A" for example. This may have also arisen from the signage used prior to the early 1960's, where the letter was painted black against a white background, with the words "STATE ROAD" above the number and the county name (in all caps) below the number. Likewise, this error may have arisen from similarly designated roads in Wisconsin being county roads. SEE ALSO EXTERNAL LINKS
