  • The bridge comprises of two spans of 100 meter each and will be launched over National Highway – 48 (connecting Delhi, Mumbai & Chennai) near Nadiad
  • This 14.3 m wide and 14.6 m in height, steel bridge weighs around 1500 MT (each span) and has been fabricated at Salasar workshop near Hapur, U.P.
  • The jointing of steel members is done using Tor Shear Type High Strength Bolts (TTHSB) designed for a 100-year lifespan
  • The spans of the bridge are painted with C-5 system painting which is first-of-its-kind in India
