North Arm Bridge, @copyright Translink (COWI client)
COWI has signed a contract for the preliminary and detailed design of an extra-dosed bridge over river Hooghly at Kalyani in West Bengal, India. The bridge will be crucial to enable growth in the area, where several Academic Institutes will be established.
The existing Kalyani city has proposed to be a model town for future development where Institute of Medical Science and Academic Institutes are to be established. Introduction of this project corridor will impart significant economic surge into the locality and adjacent society will benefit immensely.
Expected huge traffic projection along the existing project route has necessitated the requirement of the proposed extradosed Bridge as link to complement the existing bridge. The overall project corridor, in turn connecting National Highways NH2 and NH34, will carry industrial zone bypassing main cities.
''Winning the project is of paramount importance in paving a path for executing specialised bridge project in highly focused Indian Transport market. Very exciting indeed for COWI India Bridge Team to be involved in this prestigious project,'' says Debasish Ray, Head of Section Bridges, COWI India.
The bridge will be crossing the Hooghly River north of Kolkata with five main spans of approximately 120m covering overall length of 676m and able to carry six lanes of traffic. Extradosed Bridge type is a cross between Girder and cable stayed type of bridges and is the most suitable type of bridge for this proposed span. The Client is RITES Limited, Highway Division, Kolkata, who will also undertake the remaining consultancy services for a greater infrastructure expansion scheme inclusive the main road leading to the bridge. The end client for the project is West Bengal Highway Development Corporation Ltd.
"We are very proud to have been awarded the design of this important bridge project in India. It will strengthen our position as the leading international bridge designer and it will strengthen the cooperation between COWI's bridge design units in India and Denmark further," says Henrik Andersen.
COWI has significant experience with design of major bridges worldwide, presently ranked no 1 in Engineering News Record, and the Hooghly River bridge design will specifically utilise COWI's vast design experience within stay cable and concrete bridge design in both India and internationally. The design will thus be an integrated effort in COWI's offices in India and in Denmark, drawing upon COWI's global pool of skilled bridge designers. In a strong teamwork, they will design an aesthetically pleasing extension to the infrastructure in the State of West Bengal. An example of an extradosed bridge is the link from Vancouver to Richmond, British Columbia, Canada (illustration).
This project also adds to the already consistent list of COWI involvement in Bridge design in India, such as the detailed design of a cable-stayed bridge over river Yamuna at Naini – Allahabad or proof checking services of a Balance cantilever bridge over river Ganga – Bihar, and which started with the Noïda toll bridge in 1994. This project will further enhance COWI's leading position as major bridge designer in India.
The concept design will start immediately and the submission schedule for approval of the last part of detailed design is by August 2016.
