Footbridge in La Roche Sur Yon, France by Bernard Tschumi and Hugh Dutton

Friday, February 18th, 2011

The arrival of the high-speed train in the city is considered an important event and an expression of an image of modernisation. The new bridge replaces an existing one that is a standard railway bridge design that can be found all over France. This bridge type was contemporary with and inspired by the work of Eiffel. It involves the using lateral beams composed of a diagonal mesh of small plate strips that are riveted together.

The design of the new bridge uses the same language of a diagonal mesh, but in a tubular from, to create a complete cylindrical volume through hich the users pass. Footbridges over railways require lateral protection for safety of both the users and the trains below. The complete volume provides a single structural solution that possesses the necessary inertia to span between the available support points as well as provide support for the required protective screens and a canopy cover.
