摘要：	Construction of bridges in hilly areas poses unique problem to engineers. Each bridge site has its own peculiarity and need specialized approach to deal with the situation. Deep gorge, fast flow of water, bouldery river bed, geological and topographical features however makes the task of construction agencies tedious. Insuch situation, long span bridges designed on segmental construction technique has been found very effective and efficient arrangement. BRO which is primarily engaged in development of road infrastructure in hilly areas faces this problem in a major way. Large number of long span bridges has been undertaken for construction using segmental construction technique. Variety of span arrangement viz continuous, balanced cantilever and cantilever on open, well foundation and with/without monolithic construction with sub-structure has been adopted. All these bridges have been constructed using cast-in-situ construction, as limited space availability and difficulty in transportation do not favour adopting pre-cast segmental construction. This paper presents a case study of bridge undertaken for construction using cast in situ segmental construction technique and various aspects related to construction of such bridges.
