Flying junction

A Überwerfungsbauwerk or crossing structure is a bridge, an underpass, an artificial terrain incision, a tunnel, or other structure whose primary task the leadership of two overlapping transport pathways at different levels through an intersection point is.

Railway

Frequently Überwerfungsbauwerke encountered in railway construction. The long braking and acceleration distances of rail vehicles make an independent guide of different tracks especially important, for example to line tracks from a group of station tracks to complete it without the extension end on them trains block the paths for other tracks. Eisenbahnüberwerfungen need due to the low potential gradient of the access ramps often much floor space.

Auto transport

Also motorways with their completely without crossing out roadways make a variety of Überwerfungsbauwerken necessary, such as in all types of construction of the motorway junction.
