Second Iswar Guptu Setu Bridge

The project scheme consists of a greater infrastructure scheme connecting Highway No. 13 and NA No. 34 north of Kolkata, West Bengal, India. A part of the scheme consist of a dual three lane road carrying extradosed concrete bridge with a span length of typically 120 metres and a total length of 700 metres. The bridge crosses Hooghly river west of Kalyani. 

DISSING+WEITLING developed the concept for the bridge together with COWI. The bridge design is undertaken by COWI while the client undertake the consultancy services for the remaining scheme. 

The concept comprised a modern and elegant extradosed bridge with inclined double pylons. The inclined pylons gives an unique drivers experience. The bridge is supported on pile foundations where significant scour conditions has been catered for in the design. The continuous precast segmental girder is monolithically connected with four central pylons and supported on bearings at the outer most pylons and transition piers with expansion joints only at the abutments.

The bridge is located near a seismic fault line demanding that capacity design is adopted for the bridge
