PWD officials say that the consultants will first do an inspection of these flyovers and then carry out tests to assess the strength and condition of the structures. “We have asked them to prepare the reports in three months’ time. Based on the report, we will plan the rehabilitation work. The repair work will start next year,” added the PWD official cited in the first instance.
There are 86 flyovers on PWD roads across Delhi, of which 11 were constructed in the 1980s and the ’90s. After problems were reported in the Lajpat Nagar flyover last year, PWD made visual inspection of several flyovers.
While repair work on several flyovers such as Akshardham, Lajpat Nagar, Meera Bagh and Defence Colony have been completed, the department is in the process of repairing other flyovers. In East Delhi; it has started repair work on the Shreshtha Vihar flyover and will soon start the work on Nand Nagri flyover.
HT recently reported cracks in the Nehru Nagar rail Road Over Bridge (ROB), which is nearly 50 years old, near Ashram in south Delhi. Delhi PWD is in the process of preparing estimates for its repair. According to PWD officials, the repair of Nehru Nagar ROB will cost close to ₹15 crore and will start early next year.
Road safety and transport planning experts stress the need for regular maintenance of road infrastructure in the city. “These flyovers are located on arterial roads with high vehicular load. Chirag Dilli and Kashmere Gate are used by heavy vehicles, as these are located on the Outer Ring Road. The government should devise a plan for regular maintenance of flyovers. While new flyovers are being constructed in the city, it is important to repair and rehabilitate old ones as structural defects can lead to failure of the structure, ” said Sewa Ram, professor of transport planning at the School of Planning and Architecture.
