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:
“The heartless and enormous Outer Black ...”
—Robert Frost (1874–1963)
“I do not like football, which I think of as a game in which two tractors approach each other from opposite directions and collide. Besides, I have contempt for a game in which players have to wear so much equipment. Men play basketball in their underwear, which seems just right to me.”
—Anna Quindlen (b. 1952)
