Bridges are structures spanning horizontally between supports. It provides connection over an obstacle without interrupting the way below. The required connection may be for a canal, road, railway, pedestrians or a pipeline and the hurdle below can be a valley, road or river. The basic function of bridges is to carry vertical loads. The overview of the bridge seems very simple having a beam resting on two supports. The main objectives of carrying out this research work is to identify the most economical superstructure for two-lane bridge with and without footpath. In the present study four types of super structure i.e. Rectangular box girder, Trapezoidal box girder, I– Beam girder and T- Beam girder have been considered for two-lane simply supported RCC bridge of span 15m with and without footpath. All the analysis and design have been done in STAAD.Pro. The study revealed that overall cost of the bridge is minimum when we considered trapezoidal box type super structure for span 15m with and without footpath.
