The Øresund Bridge is a combined railway and motorway bridge between Denmark and Sweden. It is the longest in Europe with both roadway and railway combined in a single structure, and is one of the most central infrastructures in Scandinavia. An ambitious plan has been revealed to make this infrastructure the world’s most sustainable bridge. 3,000 m2 of solar panels are already installed by the foot of the bridge; the plan is to add an additional 10,000 m2, which will produce enough power through solar energy to cover nearly half of the bridge’s energy consumption by 2023. These panels will be located on Peberholm, an artificial island in the Danish part of the Øresund strait. Maintenance and operation of the bridge are already claimed to be climate positive, with vegetation and biodiversity surrounding the bridge capturing around 500 tons of CO2 every year. This is more than the 350 tonnes of CO2 that the bridge emitted in 2021. Since 2020, all trains crossing the Øresund Bridge have been powered by green wind powered electricity. Last year, the Øresund connection consumed approximately half of the energy it consumed in its first full year. https://stateofgreen.com/en/news/the-oresund-bridge-en-route-to-becoming-the-worlds-most-sustainable/
