Queensferry Crossing Bridge - Edinburgh, United Kingdom

This bridge crosses the Firth of Forth near Edinburgh and replaces the existing suspension bridge (Forth Road Bridge), which was found to have structural deterioration problems in addition to not having a wind screen, which caused regular closures because of high wind conditions in the area. arial
