Hydraulics of bridge is first step of bridge planning and involves lengthy calculations to assess maximum flood discharge, highest flood level and maximum velocity by using data obtained from field such as topography of bridge site, bed material, strata available for foundation, annual rainfall in catchment area, highest observed and ordinary flood levels, bed slope, etc. All these parameters are required to assess forces acting on bridge structure to make it sustainable in severe conditions. After hydraulic calculations, we move to planning of bridge structure, i.e., deciding span arrangement, slab thickness, type of foundation, pier and abutment sizes, bearings, return walls, railing, wearing course, etc according to standard type plans prepared by the Indian Road Congress for National Highways and Bridge Design Organisation of Govt. of Maharashtra for bridges on State Highways, District and village roads in Maharashtra. An Excel program has been specially prepared for hydraulic calculations and further extended to design of piers, abutments, slabs, bearings and to work out cost of bridge along with its approaches. Thus, this program can be an excellent tool to work out techno-economic feasibility of proposed bridge. For the purpose of this study, a case of construction bridge on river Kavathala in Chimur Town, Maharashtra has been considered and accordingly, a Microsoft Excel program is created for hydraulic calculations and further extended to design of various components of bridge. This program is universal and can be used for any similar bridge proposal after erasing old data and feeding new data in Excel sheet named as �New Case�. Data taken from this sheet is linked to hydraulic calculation sheets and further linked to bridge components� design sheets. Thus, any change in basic data reflects in every sheet. Any mismatch of data or value beyond specified range is displayed as �????� in sheet named as �Check�, thus error in data feeding or output which is out of range is eliminated.
