The Allegheny County Belt System color codes miscellaneous county roads to form a unique system of routes in Allegheny County, Pennsylvania and around the city of Pittsburgh.
Unlike many major American cities that utilize number-coded limited-access roads to form belt systems, the belts in the Allegheny County Belt System are not intended to be used as a high-speed routes. Rather, the belt system is to be used as a navigational aid for motorists in unfamiliar portions of the county. Roads that make up the Belt System retain their previous names. The five original routes are, from outermost to innermost, the Red, Orange, Yellow, Green, and Blue Belts. The Purple Belt was not part of the original system and was added later.

Famous quotes containing the words allegheny, county, belt and/or system:
“Wachusett hides its lingering voice
Within its rocky heart,
And Allegheny graves its tone
Throughout his lofty chart.
Monadnock, on his forehead hoar,
Doth seal the sacred trust,
Your mountains build their monument,
Though ye destroy their dust.”
—Lydia Huntley Sigourney (1791–1865)
“Hold hard, my county darlings, for a hawk descends,
Golden Glamorgan straightens, to the falling birds.
Your sport is summer as the spring runs angrily.”
—Dylan Thomas (1914–1953)
“Boss, life is trouble. Only death is not. To be alive is to undo your belt and look for trouble.”
—Michael Cacoyannis (b. 1922)
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (1817–1862)
