The third party audit of the bridges were undertaken, first for all mega bridges, railway bridges with ORN one ratings, ROBs and FOBs, second for railway bridges with ORN two ratings and bridges with speed restrictions, third for all important bridges more than 80 years old and for any other bridge which railway consider critical from the condition point of view.

The official said that the major benefits for the third party audit was realised in Mumbai area where dilapidated conditions were noticed in 49 ROBs, adding essential repairs were carried out in 43 ROBs while six ROBs were closed, dismantled and their rebuilding is under progress.

Simultaneously, dilapidated condition was noticed in 127 FOBs and essential repairs were carried out in 95 FOBs and 32 FOBs were closed and dismantled for replacement.
