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.

What distinguishes the construction method of the Austrian bridge from traditional methods?

• It uses horizontal scaffolding.

• It is constructed underwater.

• It is built vertically with scaffolding.

• It is made entirely of wood.

What is the role of the hydraulic systems in the bridge construction?

• To transport materials.

• To slowly lower the piers.

• To lift the bridge into place.

• To paint the bridge.

What happens to the steel girders as the piers are lowered?

• They are replaced with wooden beams.

• They are painted.

• They are removed.

• They unfold to form a horizontal position.

What additional material is added to complete the bridge structure?

• Concrete

• Plastic

• Wood

• Glass
