With several old flyovers in Delhi showing signs of distress due to increased load of vehicles,the Public Works Department (PWD) has decided to take up the task of repairing them,especially the ones that are more than 10 years old.
Work has already begun at Raja Garden flyover,and similar repairs are expected to be carried out on flyovers in Defence Colony,Moti Bagh and Ashram,among others.
There are around 90 flyovers in Delhi,of which nearly 25 were constructed in the last five years. They do not require any repair work. The rest ,which are more than 10 years old,need work. PWD will first carry out an inspection of such flyovers and hire consultants for advice on how to proceed with the rehabilitation. The expansion joints and bearings on the flyovers will need to be changed as increased load leads to greater wear and tear, a PWD official said.
Officials said the inspections would help them compile data better. A survey of flyovers will also ensure that we have proper compiled data on the last repairs carried out on most of our flyovers.
Officials said many flyovers,which had been constructed by other agencies such as municipal bodies,had also been handed over to PWD for repair.
The Raja Garden flyover was constructed by the municipal corporation 25 years ago. We have started repair work there,for which one carriageway had been closed partially, the official said.
PWD officials said the civic body had sought permission from the traffic police to carry out the repairs as it would require them to close one of the carriageways on each flyover.
Traffic will have to be diverted to the Defence Colony,Ashram and Moti Bagh flyovers. The permission to start work on Moti Bagh flyover has been given by the traffic police. But we are yet to start work as Metro construction in the area has already slowed down traffic there. We are looking at the best-case scenario to prevent any chaos along this stretch, the official said,adding that work would also be taken up on Wazirabad bridge.
According to traffic police,permission for repair is given depending on the requirement to carry out such work.
Work of this nature cannot be ignored,otherwise it will lead to bigger problems later, a traffic police personnel said.
A fire in the Defence Colony market had left the lower portion of the flyover there completely blackened,with concrete being chipped in several places. Repair of the slab has been taken up but changing of the bearings and joints will require the entire deck to be lifted,leading to traffic diversions .
