A section of the newly built Delhi-Dehradun Expressway caved in following overnight rainfall, prompting concerns over the quality of construction after videos of the damaged stretch circulated widely on social media. The National Highways Authority of India (NHAI) said the affected stretch has since been repaired and traffic movement restored.
NHAI attributes cave-in to waterlogging
According to the NHAI, the cave-in was caused by localised waterlogging after heavy rainfall and the inability to operationalise a permanent cross-drainage system because of resistance from local residents. The authority said the damaged stretch was identified during routine patrols and repaired immediately, allowing traffic to continue without interruption.
The NHAI stated that a balancing culvert intended to drain rainwater could not be commissioned due to resistance from local residents, who had been using the culvert opening as a vehicle crossing. It also said permanent slope protection and drainage works remain stalled because of a land-related arbitration dispute with landowners.
Interim drainage measures put in place
As an interim arrangement, the NHAI said it has constructed a 1.5-km parallel drain and is redesigning the drainage system to safely channel rainwater until the permanent drainage infrastructure is completed.
The authority added that the site is being monitored continuously and that pending permanent works will be undertaken once the land dispute is resolved.
Expressway inaugurated earlier this year
The 210-km Delhi-Dehradun Expressway was inaugurated by Prime Minister Narendra Modi in April 2026.
The cave-in triggered public concern over the durability of the newly operational expressway, with social media users questioning how a flagship infrastructure project could sustain such damage within months of opening. The NHAI, however, maintained that the incident was linked to heavy rainfall and temporary drainage constraints, and said repairs were completed promptly with traffic restored.
