MALKANGIRI: Keeping in view the water level in Chitrakonda reservoir, the Government has changed the design of Gurupriya bridge being constructed over river Janbai in the cut-off region, on the other side of the reservoir. To prevent further tilting of piers as it had happened with pier No.13 a few months back, the Works department has effected certain changes in the design. In the revised design, 24 piers, instead of 23 piers, will be erected thus reducing the foundation distance from 40 metres to 30 metres from piles 11 to 14, which will be erected in the deep water zone. Similarly, in place of concrete girders, steel girders will be made for the piers from 11 to 17 to minimise the load, Works department sources said. The number of piles to be constructed too has gone up from 112 to 136. Jeypore-based Superintendent Engineer N C Dora, Executive Engineer Arun Kumar Sahu and Royal Infra Constru Limited Super Stricture Designer S M Ghosh visited the site of the bridge on Saturday in the backdrop of change in the design.
