Inner/outer directions are labels that identify the direction of travel on opposing lanes of traffic on certain ring roads and beltways. They can be used to sign individual routes that encircle a city or metropolitan area, where east–west and north–south orientations cannot be applied uniformly. The labels are also used in select double track rail systems that form a loop, indicating the direction of travel of each line.
Variations of the labels include "inner loop"/"outer loop", "inner beltline"/"outer beltline", "inner ring"/"outer ring", "inner rail"/"outer rail", and "inner circle"/"outer circle".
In 2009, Interstate 277 in Charlotte, North Carolina became the first non-contiguous loop route to utilize inner/outer directional signage.

Famous quotes containing the words outer and/or directions:
“When human beings have been fascinated by the contemplation of their own hearts, the more intricate biological pattern of the female has become a model for the artist, the mystic, and the saint. When mankind turns instead to what can be done, altered, built, invented, in the outer world, all natural properties of men, animals, or metals become handicaps to be altered rather than clues to be followed.”
—Margaret Mead (1901–1978)
“My friend devotes himself to his life, whenever he can find the spare time. His motto is: ‘Don’t just sit there: live!’ So he’s too busy to stand, to walk, to do anything, except to live. He even refused to kiss a girl, when invited, on the grounds that it was time again to be living. Schedules are sacred to him.”
—Marvin Cohen, U.S. author and humorist. The Self-Devoted Friend, New Directions (1967)
