22 Jul 11: Recent periodic inspections of 45 flyovers conducted by GHMC has revealed that hair line cracks have appeared on around five flyovers. Apart form that, several flyovers were found with damaged bearings and loosened expansion joints. The officials also reported that the bitumen layer on the bridges was very heavy and the new layer should be laid only after removing the older one. Even some small plants have also cropped up on few flyovers.
The hairline cracks were found on flyovers of Khairtabad, Lalapet, Masabtank, Dabeerpura and Narayanguda. The structural engineers have suggested that, if these cracks on exteriors are ignored, they may deepen further, posing danger to whole structure.
Some of these 45 flyovers were constructed by GHMC and HMDA, while others by Roads and Buildings Department. It is found that, each flyover bears about 1,000 tonnes of weight every hour.
