The project entails construction of a new bridge to carry the four traffic lanes of the Inland Island Highway over the ravine formed by the Tsable River. The bridge itself is the largest in the area. It measures 400 m long and 65 m deep. The substructure is founded on 900 mm diameter by 30 m concrete piles and consists of two balanced cantilever segmental post tensioned construction method. The cross section of the bridge deck consists mainly of a single cell box. This project also includes grading work for bridge approaches on the south bank to a length of about 80 m; and on the north bank to a length of about 150 m.
