The Materials That Changed Construction Forever
Synopsis
A 122-meter-high railway deck sits on the Garabit Viaduct, the highest iron arch bridge in the world, built in the 19th century.
Synopsis
Dr. Scott Steadman visits the Garabit Viaduct in France, a landmark of 19th-century engineering. The bridge, designed by Gustave Eiffel, measures 563 meters long and stands 122 meters high. It exemplifies the use of wrought iron, allowing for new heights in railway construction. Steadman discusses the innovations in material science that enabled this and similar structures. The film also addresses the contributions of other engineers, including Sir Benjamin Baker, in reshaping modern architecture.
