KOLKATA: The Kolkata Metropolitan Development Authority (KMDA) has initiated the process to engage agencies for doing a structural condition tests and preparing DPRs for repair and retrofitting works of the Kidderpore steel bridge over Tolly Nullah and Alipore’s Dhana Dhanyo Setu.
Both bridges had been built several years ago and have not been properly supervised. “Apparently the structural condition of the two bridges seem to be alright but a thorough test including load capacity is needed to see if there has been any deterioration in its condition or whether its load bearing capacity has diminished or not,” said a KMDA official.
KMDA have completed load capacity test of several bridges in the first two phases, and both these bridges will undergo the test in the third phase. The Kidderpore bridge is a steel structure similar to Chetla Lock gate and Chitpore bridge which have both incurred damages. KMDA has also decided to dismantle Chetla Lock gate bridge and will reconstruct it at a nearby position. Same is the plan for Chitpore bridge.
KMDA is also preparing the detail project report (DPR) for replacing the damaged joint bearings of Aurobindo Setu that links Ultadanga with Gouribari crossing. The bridge that was constructed nearly 50 years back has been found to have diminished load bearing capacity.
Repair work of Kalighat setu will also start soon with the authorities presently doing the technical evaluation of the bids submitted by interested agencies to take up the work. KMDA is also on the process to engage agencies for taking up major repair work of Baghajatin ROB and a span of Ultadanga flyover.
