Overpass structures
Introduction
An overpass or elevated is a bridge, road, railway line or similar structure that crosses over another road or railway. An overpass and an underpass or tunnel form an underpass.[1] Road junctions are made up of several overpasses.
History
The world's first railway overpass was built in 1843 by the London and Croydon Railway at Norwood Junction station to carry its carriages over the Brighton line.[2].
India's first flyover was inaugurated on April 14, 1965 at Kemps Corner in Bombay. The 15-metre bridge was built in approximately seven months by Shirish Patel at a cost of ₹17.5 (equivalent to USD 820,000 in 2013).
