Development of alternative concrete bridge superstructure systems for short and medium span bridges

•Two concrete bridge superstructure systems (PS2 and PS4) are presented.•PS2 is lighter than the box beam system and features shallower depths.•PS2 also requires fewer strands and generally exhibits lower camber.•PS4 features shallower depths compared to the decked bulb tee system.•PS4 also exhibits...
