An IIT Roorkee inspection has made an important finding on the strength of the 4.8-kilometre elevated road built between Noida’s Sector 27 and Sector 61. In the preliminary inspection, only one concrete panel along the entire stretch was found to be weak. This is the same section where repeated potholes had forced the closure of traffic. The reassuring point from the inspection is that no major weakness has currently been found in the remaining parts of the road.
The IIT Roorkee team, along with an expert from the United States, carried out the inspection using ultrasonic guided waves technology. Through this modern technique, internal cracks and structural weaknesses were detected without breaking the road’s upper layer. The inspection found that the problem was not in the upper bitumen layer, but in the concrete panel beneath it, which is about 11 metres long and 2.5 metres wide.
According to the Noida Authority, the affected section will be repaired after the detailed report is received. The plan is to install shuttering from below and repair the pothole and the surrounding area. Engineers suspect that the strength of the concrete panel may have been affected due to excessive vibration during construction. However, the actual cause will become clear after the report.
One lane of the elevated road has been closed since October 21. As a result, motorists have had to use alternative routes and traffic pressure has increased.
