Abstract: The new bridge over the Orne river in Boncourt, Eastern France, is an original alternative to composite steel-concrete decks for single medium range spans. Its span of about 32 m is crossed with a prestressed girders deck composed of ITE® beams made of BSI®, and connected to a cast-in-situ conventional concrete slab. ITE® beam would stand for enlarged bottom flange I cross-section beam in French. Its particular shape and the use of UHPFRC allows for a quite slender deck structure, and a more efficient use of prestressing. The precast UHPFRC beams are supported by integral abutments, whose maintenance costs are expected to be low. The stiffness of the portal frame structure that is created this way is reduced by the use of small diameters piles for abutments foundations.
