This paper describes the design and construction of the third Pinel Bridge in France, in 2007. Located just to the west of Rouen, this small bridge has a single 27m long span and is 14m wide. It will increase the traffic capacity of an existing bridge over three railroad tracks from two lanes to five. The bridge deck combines a conventional slab of standard reinforced concrete with seventeen parallel contiguous beams made of self-consolidating ultra high performance fiber-reinforced concrete (UHPFRC). The beams - designed by the contractor Eiffage TP as an alternative to a filler- beam deck – are prestressed with 28 internal strands placed in a very wide bottom flange.
