Missouri supplemental route

A supplemental route is a state secondary road in the U.S. state of Missouri, designated with letters. Supplemental routes were various roads within the state which the Missouri Department of Transportation was given in 1952 to maintain in addition to the regular routes, though lettered routes had been in use from at least 1932. The goal of the secondary highway system was to place state-maintained roads within 2 miles (3 km) of more than 95% of all farm houses, schools, churches, cemeteries and stores. The four types of roads designated as Routes are:

Supplemental routes make up 19,064 miles (30,681 km) (59%) of the state highway system.

Highway designations

The more major supplemental routes of the system are ones assigned with single-letter designations (such as "K"). Minor branch routes and farm-to-market roads, which often end at county roads or are former alignments of the other highways, are typically assigned with two-letter designations consisting of two of the same letter (e.g. "KK"). Additionally, combinations of letters may be used, but always with A as the first letter (such as "AD"); the only exception of this is on Route BA in western St. Louis County. Combinations beginning with the letter R are also used for routes that connect with state parks or other recreational facilities, which is the only use of R on the system; Route AR, a non-recreational route south of Bakersfield, is the only exception to this.

New York State Route 990V

New York State Route 990V (NY 990V) is an east–west reference route in Schoharie County, New York, in the United States. It extends for 6.15 miles (9.90 km) from an intersection with NY 30 in the town of Gilboa to a junction with County Route 18 (CR 18) in the town of Conesville, where the road continues east as CR 3. Reference routes in New York are typically unsigned; however, NY 990V is fully signed with touring route markers. The road is a remnant of New York State Route 342, a route assigned as part of the 1930 renumbering of state highways in New York. The NY 342 designation was removed in the late 1940s; however, its former routing from Gilboa to Conesville remained a state highway and became NY 990V when the modern reference route system in New York was created.

Route description

NY 990V begins northwest of the Schoharie Reservoir at an intersection with NY 30 in the town of Gilboa. The route heads northeast around the reservoir as a two-lane highway, intersecting CR 13 (Stryker Road) in an area of open fields before crossing Schoharie Creek a short distance downstream from the Gilboa Dam. On the opposite bank of the creek, the highway quickly passes through the small hamlet of Gilboa, located at a junction with CR 17 (Flat Creek Road). Outside of Gilboa, NY 990V turns to the southeast, paralleling the eastern edge of the reservoir as it runs through a stretch of forests and passes directly south of Gilboa-Conesville Central School. The wooded areas give way to slightly more open terrain in the adjacent town of Conesville, where the route meets CR 39 (Prattsville Road) just east of the town line. CR 39 heads south from this point, taking over as the primary waterside roadway while NY 990V heads east into a valley surrounding Manor Kill.

List of Metrobus routes (Washington, D.C.)

This is a list of bus routes operated by the Washington Metropolitan Area Transit Authority (WMATA), branded as Metrobus. Many are the descendants of streetcar lines operated by the Capital Transit Company or its predecessors.

Numbering

Bus routes operating in or through Virginia are noted with a letter and a number. Bus routes operating in DC or Maryland use only a number, or a letter and a number, as noted below.

Odd-numbered routes are typically part-time variants of even-numbered routes. At one time, odd numbered routes were express routes, but that distinction has been abandoned. Most D.C. and Maryland routes are grouped by their first digit. When this system was laid out in 1936, the following clustering was used:
