- The bridge has been built by 1 lakh cubic metres of high strength, high performance concrete enough to fill 40 Olympic size swimming pools.
- 13,000 tonnes of corrosion resistant reinforcement steel, 32,000 square metres of structural steel plates and 1,800 kilometres of high tensile pre-stressing strands have gone into making the bridge.
- The bridge utilizes 88 high tensile strength cables in the state-of-art single place harp type cable stay system and a real-time force monitoring mechanism.
The bridge is constructed by the GIDC (Goa Infrastructure Development Corporation) in collaboration with construction major Larsen and Toubro.
River Mandovi, also known as Mahadayi or Mhadei river is regarded as the lifeline of Goa. The river originates from a cluster of 30 springs at Bhimgad in the Western Ghats in the Belagavi district of Karnataka and has a total 2,032 km2 catchment area of which 1,580 km2, 375 km2 and 77 km2 catchment area are in Goa, Karnataka and Maharashtra respectively. Owing to the differences over the sharing of the river water among the states of Goa, Karnataka and Maharashtra, the union government has constituted Mahadayi Water Disputes Tribunal to examine the claims made by the states.
