An overpass is a bridge, railway or similar structure that crosses over another road or railway. An overpass and underpass together form a grade separation. Stack interchanges are made up of many overpasses; the world's first railroad flyover was constructed in 1843 by the London and Croydon Railway at Norwood Junction railway station to carry its atmospheric railway vehicles over the Brighton Main Line. In North American usage, a flyover is a high-level overpass, built above main overpass lanes, or a bridge built over what had been an at-grade intersection. Traffic engineers refer to the latter as a grade separation. A flyover may be an extra ramp added to an existing interchange, either replacing an existing cloverleaf loop with a higher, faster ramp that bears left, but may be built as a right or left exit. A cloverleaf or partial cloverleaf contains some 270 degree loops, which can slow traffic and can be difficult to construct with multiple lanes. Where all such turns are replaced with flyovers only 90 degree turns are needed, there may be four or more distinct levels of traffic.

Depending upon design, traffic may flow in all directions near open road speeds. For more examples see Freeway interchange. A pedestrian overpass allows pedestrians safe crossing over busy roads without affecting traffic. Railway overpasses are used to replace level crossings as a safer alternative. Using overpasses allows for unobstructed rail traffic to flow without conflicting with vehicular and pedestrian traffic. Rapid transit systems use complete grade separation of their rights of way to avoid traffic interference with frequent and reliable service. Railroads use balloon loops and flying junctions instead of flat junctions, as a way to reverse direction and to avoid trains conflicting with those on other tracks.
