Three unique composite bridges are described, which feature different construction methods and structural systems, and have spans ranging 120 ft to 10,000 ft. The Roize bridge on the motorway between Valence and Grenoble, France,is an experimental bridge and represents an attempt to lighten bridge decks of medium span bridges. The details are described of its design, and the superstructure which consists of a precast, pretensioned concrete deck slab supported by a steel space truss. The composite truss of the bridge is both lightweight and very stiff in resisting vertical loads. The paper also describes the Ebron Bridge, a composite haunched truss between Grenoble and Sisteron, France. A new bridge concept using both self-anchored and earth-anchored stays was developed that demonstrates the possibility of extending the limit of the maximum clear span of a stay supported deck to 10,000 ft.
