Composition
The Belt System consists of six beltways. The Purple, Blue, Green, Yellow, Orange, and Red Belts travel distances of 2 miles (3.2 km), 38 miles (61 km), 39 miles (63 km), 78 miles (126 km), 92 miles (148 km), and 34 miles (55 km), respectively. The Purple, Blue, and Yellow belts are complete circular routes, beginning and ending at the same points. The Orange Belt was a complete circle until 12 miles (19 km) of the southernmost stretch (including its entire stretch through Washington County) was decommissioned in the 1970s to keep the belt system entirely in Allegheny County. It still briefly traverses Westmoreland County in New Kensington.
Prior to its acquisition by the Chevron Corporation in 1980, the Gulf Oil Corporation, with headquarters in Pittsburgh, published a map of Allegheny County prominently displaying the Belt System. Currently, Allegheny County produces maps featuring the Belt System.

Famous quotes containing the word composition:
“At painful times, when composition is impossible and reading is not enough, grammars and dictionaries are excellent for distraction.”
—Elizabeth Barrett Browning (1806–1861)
“The composition of a tragedy requires testicles.”
—Voltaire [François Marie Arouet] (1694–1778)
“Give a scientist a problem and he will probably provide a solution; historians and sociologists, by contrast, can offer only opinions. Ask a dozen chemists the composition of an organic compound such as methane, and within a short time all twelve will have come up with the same solution of CH4. Ask, however, a dozen economists or sociologists to provide policies to reduce unemployment or the level of crime and twelve widely differing opinions are likely to be offered.”
—Derek Gjertsen, British scientist, author. Science and Philosophy: Past and Present, ch. 3, Penguin (1989)
