A cloverleaf interchange is a two-level interchange in which left turns (reverse directions in left-driving regions), are handled by ramp roads (US: ramps, UK: slip roads). To go left (in right-hand traffic), vehicles first continue as one road passes over or under the other, then exit right onto a one-way three-fourths loop ramp (270°) and merge onto the intersecting road.

Famous quotes containing the word interchange:
“What men have called friendship is only a social arrangement, a mutual adjustment of interests, an interchange of services given and received; it is, in sum, simply a business from which those involved propose to derive a steady profit for their own self-love.”
—François, Duc De La Rochefoucauld (1613–1680)
