  • 1000 mm dia RCC bored piles were constructed to a maximum depth of approx. 27.061 metre by Hydraulic Rig in hard strata.

  • In active part of river 12 mtr dia13 noswell foundation were constructed by floating caisson and sunk to a depth of 20.65 mtr through hard rock.

  • The height of the deck of the bridge is about 36 mtr from the deepest river bed level.
