The present invention relates to a system for short- and medium-span bridges. The bridge superstructure is built entirely from materials that are not vulnerable to corrosion. It consists of precast prestressed concrete truss girders and a concrete deck. The girders have top and bottom concrete bulbs (i.e. flanges) connected by precast veri:ical and diagonal truss members made of corrosion-resistant metallic or non-metallic tubes filled with concrete. The deck can be a cast-in-situ reinforced concrete slab or an assembly of precast concrete panels tied together by longitudinal and transverse post-tensioning cables. The reinforcement in the slab is glass FRP in three directions and stainless or any other corrosion-resistant steel in one direction.
