MANAS BRIDGE, BHUTAN

The bridge is located on the road that forms life line of Eastern Bhutan by running through the entire length of Bhutan connecting it with its capital, Thimpu on one side and terminating at Indian town Rangia, 53 kms off Guwahati, capital city of Assam State. The requirement of this bridge was necessitated for transporting heavy machinery for undertaking the construction of a hydroelectric power project. The main truss of the bridge is designed as triangular steel lattice girder with bottom chord prestressed by 4 Nos 12T 13HT Strands. Incidentally the innovative concept of bottom chord prestressing was introduced by us in 1993 in Bhutan. All shop joints are bolted mainly by HSFG (High Strength Friction Grip) bolts.
