The Delhi-Dehradun Expressway, a ₹12,000-crore project inaugurated by Prime Minister Narendra Modi on April 14, is facing significant structural issues. Recent reports highlight cave-ins near the Biharigarh flyover and severe soil erosion near the Dalhedi flyover in Saharanpur district, raising alarms about construction quality. Two locations on the Biharigarh flyover have subsided, leading to traffic restrictions as repairs are initiated. This is not an isolated incident; similar subsidence occurred six months ago in the same area. Locals fear that the situation could deteriorate further with the upcoming monsoon season. Additionally, severe soil erosion has created deep craters near the Dalhedi flyover, posing risks to drivers, particularly two-wheeler riders. The construction company is currently conducting reinforcement work to stabilize the affected areas. Ongoing structural concerns have been noted, including the need for strengthening 24 pillars last year, indicating a pattern of technical issues along the expressway.
