footbridge

from Wikipedia, the free encyclopedia

A pedestrian bridge , also known as a pedestrian overpass , passerelle , gangway or as a closed construction skyway , leads sidewalks over bodies of water , traffic systems or valleys . They can be built from various building materials . They are available as static bridges as well as movable constructions (for example bascule, swing or lifting bridges). The dimensions range from a few meters to a span of several hundred meters . Due to the low loads and the mostly small spans, there is often a high degree of design freedom when designing pedestrian bridges.

Traffic safety and traffic planning

From the point of view of traffic safety and traffic planning, pedestrian bridges also serve to separate different traffic flows, such as those resulting from motor vehicle traffic, rail traffic and pedestrian traffic . Pedestrian bridges allow motor vehicles and rail vehicles to move smoothly and protect pedestrians when crossing streets and rail tracks. Because of the cost-intensive construction, they are mainly found in places with a high volume of traffic and high traffic speeds such as through streets, city highways or train stations.

Despite the increased safety, pedestrians sometimes prefer the level road or rail crossing (pedestrian crossing, pedestrian path) to an overpass or underpass because of the necessary detours and the difference in height. For this reason, additional structural measures such as bars, fences and other barriers are used in some places.

Examples

Architecturally outstanding

Extreme location

  • In Reutte , Austria , the highline179 was 403 meters long - slightly diagonally across the valley - Europe's longest pedestrian suspension bridge before it was replaced by the Charles Kuonen suspension bridge . The bridge connects Ehrenberg Castle and Fort Claudia and is accessible around the clock. To prevent overloading, access on both sides via counting turnstiles is limited to a load capacity of 500 people.
  • The Yume (Dream) pedestrian suspension bridge at Kokonume in the Japanese prefecture of Ōita has a span of 390 meters.
  • The AJ Hackett Skypark, which opened on July 1, 2014 in Sochi , Russia , has a 439-meter-long SkyBridge .
  • On May 7, 2017, the Titan RT bridge opened at the Rappbodetalsperre in the Harz Mountains ; The 483 m long structure had, at 458.5 m, the longest free-hanging section of all pedestrian suspension bridges in the world until July 2017.
  • The Charles Kuonen suspension bridge in Switzerland has been the pedestrian suspension bridge with the longest free-hanging section in the world since July 2017: 494 m. For years the European route between Grächen and Zermatt was interrupted after a rock fall.
