The Gurugram-Sohna Highway caved in again on Monday, marking the seventh such incident on the key link in three years and forcing the closure of one of its three lanes as authorities moved to prevent accidents and manage traffic disruption.
Officials from the National Highways Authority of India (NHAI) and Gurugram traffic police reached the site after a section of the road near SD Adarsh School developed a pit. The affected stretch was barricaded and traffic was stopped on the damaged lane. The restriction slowed vehicles during the evening peak and raised fresh concerns among motorists using the highway to access the Delhi-Mumbai Expressway.
The recurring damage has been linked to a main sewer line running from the Sheeshpal Vihar Society towards Subhash Chowk. The line, laid around 30 years ago, carries sewage from sectors 45 to 51 to the sewage treatment plant at Behrampur. It lies approximately 22 to 25 feet below the road and has reportedly deteriorated significantly.
The latest damage involved a pit approximately 2.5 to 3 feet wide. Representatives of the company that constructed the highway and NHAI officials inspected the location before the lane was closed. The source report contains differing references to when the latest cavity was first noticed, but identifies the current incident as the seventh road failure on the highway in three years.
The earlier incidents were recorded on June 18, June 30, July 2 and December 24 in 2024, followed by June 18 in 2025 and May 6 in 2026. The road had reopened about one-and-a-half months ago after repairs that began in August and kept the affected stretch closed for around four months. Its renewed failure has therefore brought the durability of repeated surface repairs under scrutiny.
The highway was constructed at an estimated cost of around ₹2,000 crore. Its importance extends beyond local traffic because vehicles travelling from Delhi use the corridor to reach the Delhi-Mumbai Expressway. A single-lane closure on the three-lane road can therefore affect both daily commuters and longer-distance traffic moving through the southern Gurugram corridor.
The proposed permanent response centres on the damaged sewer line rather than another surface repair. The Gurugram Metropolitan Development Authority prepared an estimate of approximately ₹20 crore in July 2024 for repairing the line through the cured-in-place pipe, or CIPP, method. A tender submitted at 35 per cent above the estimated amount was cancelled after the issue was raised in a high-level meeting chaired by the chief minister, according to the report.
A subsequent decision assigned the sewer-line repair to NHAI, with the cost to be borne by GMDA. NHAI has prepared a revised estimate of about ₹58 crore, which GMDA has approved. The arrangement places the recurring road damage within a wider coordination problem involving the highway authority, the metropolitan development authority and an ageing urban sewer network beneath a major transport corridor.
Yogesh Tilak, NHAI project director, said the permanent repair would begin soon and be completed by February. He said the sewer line would be repaired using the CIPP method and that the method would prevent further damage to the line and, consequently, further road cave-ins. Until that work is completed, the affected lane remains the immediate focus of traffic management and safety measures.
