516 Arouca is a pedestrian suspension bridge in Arouca in northern Portugal . At 516 m in length, it replaces the 494 m long Charles Kuonen suspension bridge (Valais, Switzerland) as the longest pedestrian suspension bridge in the world. It crosses the gorge of the Paiva River at a height of 175 m. Depending on the source, it is also considered to be the second longest pedestrian suspension bridge in the world after the Baglung Parbat suspension bridge in Nepal.

Emergence

The first ideas for the bridge came in 2005, when it was part of a geopark . This became the Arouca UNESCO Global Geopark in 2015 and has an area of ​​327 km². The bridge is located in this. The ITeCons - Institute for Research and Technological Development for Construction, Energy, Environment and Sustainability at the University of Coimbra was responsible for design, computational and experimental analysis, dimensioning and technical support during construction. The Laboratório Nacional de Engenharia Civil (LNEC) carried out tests in the wind tunnel and on site to verify safety. The bridge was built by Conduril - Engenharia, SA . Conduril's subcontractors included Cordoaria Oliveira Sá , a subsidiary of the American WireCo WorldGroup, responsible for the production and installation of the entire cable system, and Outsideworks, which specializes in vertical work, for work at height . The European Union supported the project.

Planning began in 2016 and construction began in 2017. Due to execution problems and geological difficulties, the originally intended location of the bridge had to be relocated. The bridge was completed in July 2020. The construction costs amounted to approx. 2.1 million euros. The opening was set for May 2, 2021; Locals were able to enter it from April 29, 2021.

The bridge consists of a total of 127 metal grid modules, each 4 m long, so that one can see well through the ground into the deep gorge of the Paiva River below . It is supported by two steel cables on two reinforced concrete - pylons are fixed at the beginning and end of the bridge. The pylons are 35.5 m high and have the shape of a cut upside-down "A"; on the top they are 32 m wide. This reduces horizontal vibrations.

classification

While the bridge is largely referred to as a pedestrian suspension bridge , CNN also gives “ Tibetan Style ” (CNN, German: “Tibet-style”) for classification. The Charles Kuonen suspension bridge is also referred to in its entry in the Guinness Book of Records as the “ Longest Tibet-style footbridge ” (Guinness Book of Records, German: “Longest pedestrian bridge in Tibetan style”).

use

The bridge is closed to children under 6 years of age, minors must be accompanied by their parents. Adults must also be accompanied by a tourist guide. A crossing costs € 12 (as of May 2021).

The bridge is owned by the municipality of Arouca.

Awards

The bridge was awarded the Portuguese architecture prize “Prémios Construir” in 2020 and is nominated for one of the World Travel Awards in 2021 .
