A portion of the newly built Delhi-Dehradun expressway caved in near Shamli on Wednesday morning after overnight rainfall, prompting widespread circulation of videos on social media and renewed concern over motorist safety and the durability of a flagship infrastructure project only months after it became operational. The incident occurred at Gogwan Jalalpur village in Shamli and drew attention to drainage and construction issues along the corridor. The National Highways Authority of India said the damaged stretch had been repaired and attributed the cave-in to localized water stagnation and constraints in integrating the cross?drainage system at the site. The authority explained that a culvert had been constructed to carry rainwater from the expressway but that the drainage could not be integrated because local residents had been using the culvert opening as a vehicular crossing. It also said permanent slope protection and chute drain works remained pending owing to an ongoing land arbitration dispute. To address immediate risks, the authority reported that it had initiated construction of an interim parallel drain of approximately one and a half kilometres and was redesigning the drainage gradient to convey rainwater safely to the entry and exit location at kilometre 56+500, pending commissioning of the balancing culvert. Repair teams restored the road surface promptly and traffic was managed to minimise disruption while engineering works continued. The 213 km expressway was built at a cost of around Rs 120 billion and was inaugurated on 14 April by Prime Minister Narendra Modi. It has reduced travel time between Delhi and Dehradun to about two and a half hours from the earlier six and a half hours and is designed for a maximum speed of 100 kmph. The route connects with major expressways including the Delhi-Mumbai, Delhi-Katra and Delhi-Meerut corridors and will link to future projects such as the Gorakhpur-Shamli Expressway and the Haridwar Spur.
