Summary, etc. The Indian designers and contractors preferred long span concrete girder bridges constructed by cantilever method of construction to span rivers, strait crossings, ravines and gorges, for overcoming the foundation problems and to provide navigational clearance, etc. Barak Bridge at Silchar built in 1961 was first of this kind constructed by cantilever cast-in-situ segmental construction method in India. Since then many cantilever girder bridges using cast-in-situ or precast segmental technology have been constructed, the longest span being 165 m. The design and construction technology warranted for extradosed bridges is akin to cantilever bridges. Thus for having perfected the technology over the period, it was an organic choice for Indian designers to go for extradosed bridges which has a striking similarity to that of cable stay bridges.

Hence, there is a spurt of burgeoning of Extradosed bridges in the country due to its innate design and construction friendly nature. Siddapur bridge at Coorg in Karnataka is the first indigenously designed and constructed by cast-in-situ cantilever construction method extradosed bridge in India. At the same time Indraprastha, Moolchand bridges by DMRC and 2nd Vivekananda bridge at Kolkata which were designed by expat consultants & realized by pre-cast segmental construction technology were under construction.

Logically, the organic evolution of cable supported bridges should have been in the order of girder bridges to suspension bridges or otherway round. But in reality, the suspension bridges gave rise to cable stay bridges and cantilever girder bridges was conceptually was extrapolated to extradosed bridge despite its striking visual similarity with cable stay bridges.
