KANPUR, July 6 -- A link road connecting the Ganga Expressway with the Sonic toll plaza in Unnao was damaged in the season's first spell of heavy rain, raising fresh questions over the quality of construction barely two months after the Rs.12,000-crore expressway was inaugurated. The seven-metre-wide approach road on the Meerut-Prayagraj carriageway near kilometre 421 developed a washout after heavy rain on Friday, with soil along the embankment eroding and part of the carriageway collapsing. By Saturday, more soil had been washed away from the roadside, a traffic sign had fallen, and sections of the roadside drain were found damaged. The damaged stretch was repaired on an emergency basis on Friday and Saturday. However, fresh erosion at the same spot raised concerns over the stability of the embankment. Locals alleged that slope protection measures, including the grass cover meant to prevent soil erosion, were either inadequate or missing. Patel Infrastructure project manager Satish Singh said such issues could occur after the first spell of heavy rain. "The eroded portion will be repaired. We have no information about the fallen signboard, but that too will be rectified," he said. The incident is the latest in a series of defects reported on Ganga Expressway. Even before PM Narendra Modi inaugurated the project on April 29, instances of subsidence, soil erosion and damage to service lanes had been reported at several locations near Sonic, following which repairs were carried out....
