Editing Overpass (section)

==Railway==
Railway overpasses are used to replace [[level crossing]]s (at-grade 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 [[Right-of-way (transportation)|rights of way]] to avoid traffic interference with frequent and reliable service.

Railroads also use [[balloon loop]]s and [[flying junction]]s instead of [[flat junction]]s, as a way to reverse direction and to avoid trains conflicting with those on other tracks.
