Futuristic new bridge unfolds like an umbrella

The video tutorial explains the construction of a unique bridge in Austria, built vertically instead of horizontally. Engineers used scaffolding to erect two vertical concrete piers and attached steel girders on both sides. The piers were then lowered using hydraulic systems, allowing the steel girders to unfold and reach a horizontal position. Concrete was added to complete the structure, resulting in the 116-meter Lafnitz Bridge, which was unfolded over the Lafnitz River on February 27th, 2020.
