It is supported by 88 cables on a single plane, harp type cable-stayed arrangement.  Each of the four pylons stand on individual concrete pile foundations. The piles are 1.5m in diameter and in groups of 16 and 20 nos in the central and extreme pile caps respectively.

The bridge has a 21m wide 4-lane deck comprising of 190 individual precast segments. The segments were manufactured at L&T’s precast manufacturing unit located at Dhargal, 22km from the main site.
