Elevated road

from Wikipedia, the free encyclopedia
Hochstraße in Ludwigshafen
Zurich's Sihlhochstrasse runs over the Sihl river to save space .

An elevated road is a section of road that runs at a higher level than the terrain surface or the other main traffic level, i.e. H. which is usually carried out on viaducts or dams (with bridges in between ) or other supporting structures.

A high road is not to be confused with a high road (mountain road) .

Elevated roads are used to lead higher-level roads (motorways or federal highways) without disturbing junctions with subordinate roads by placing them on a different level ( freedom from height ). This is associated with complex junction points with ramp structures. The height is usually more than five meters.

In order to effectively minimize the propagation of noise on the overpass, noise protection systems must be installed on the overpass in accordance with the rules applicable in Germany. In addition to the high construction and maintenance costs, the appearance is often criticized. Integration into the cityscape or landscape is insufficient despite various design measures. Therefore, in some places inner-city elevated roads were torn down again and replaced by "ordinary" roads or tunnels, for example in Düsseldorf (see millipedes ) or Bruck an der Mur .
