Enhancing connectivity in West Bengal
The project is part of a greater infrastructure scheme connecting Highway No. 13 and NA No. 34 north of Kolkata, West Bengal, India. The National Highway 34 is considered to be the lifeline of North Bengal – the new bridge will make it possible to reach Nadia in only 30 minutes time.
A part of the scheme consist of a dual three lane road carrying an extradosed concrete bridge with a span length of 120 metres and a total length of 700 metres. The bridge crosses Hooghly river west of Kalyani.
The bridge design
The concept comprise an elegant extradosed bridge with inclined double pylons - offering an unique drivers experience. The bridge is supported on pile foundations where significant scour conditions have 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.
The bridge concept won a 1st prize in an international competition in 2015.
