Vehicle population in cities of India is increasing at a fast rate. As result of rapid growth smart solution required for cites infrastructural growth, all of which require to be integrated with public transport. Various researches and development are held by researchers to find economic and time saving technic of constructions. Precast concrete is one of those researches. The favor of precast method in construction has increased worldwide in the last few decades. This method of superstructure casting in metro projects offer multiple advantages to owners like reduced costs, reduced construction time, reduced environmental impacts, and reduced maintenance of traffic. Infrastructure projects like Metro, flyover alignments are fixed and constructed in high dense traffic areas where diversion of road either costly or not possible. With precast we can solve traffic diversion or road block issues while construction of any infrastructure project. The construction of both medium and long span precast concrete segmental spans is widely spread throughout India for metro projects. This method can also be taken in highways, railways, and rapid transit, in both urban and rural area. Alignment can be straight or curved, and can implement in long spans for difficult obstructions and territory. This paper reflects the various types of precast superstructure. Also from the points of cost, time and safety, this paper contributes to promote the use of high performance concrete, and to optimize the design and the casting of precast segmental spans, especially precast viaducts built by precast segmental method.
