Traffic diversion on Delhi-Dehradun highway till June 8

Traffic diversion: There is a big update for everyone.  Travelers using the Delhi-Dehradun Economic Corridor should brace themselves for some challenges in the upcoming weeks. Work to stabilize the hillside is set to commence on the Ganeshpur-Dehradun stretch, leading to traffic diversions over roughly 1.25 kilometers of the highway. This process will start on May 22, 2026, and is expected to last until June 8, 2026.

The highway traverses mountainous regions, where significant rock cutting was performed during the road widening efforts. This creates a potential risk of rockfalls in certain vulnerable spots. The NHAI has already put in place stone catchers at these areas, but it deemed it necessary to further reinforce the slopes ahead of the rainy season. Consequently, work to scale the mountain slopes and clear away excess debris has now commenced. Additionally, more forest land has been allocated for this initiative.

What route will traffic follow?

Vehicles heading towards Dehradun will be shifted from the left lane to the right lane at kilometer 14+650. After traveling about one and a quarter kilometers on the right lane, they will switch back to the left lane at kilometer 15+900, just before the Daat Kali Tunnel.

Vehicles returning to Delhi and Saharanpur will be redirected to the old highway after passing through the Dat Kali Tunnel. After covering approximately 1.3 kilometers on the old route, they will rejoin the right lane of the corridor at kilometer 14+650.

Passenger convenience is also a priority

To minimize confusion during the diversion, flagmen will be stationed around the clock to assist drivers. The remainder of the highway will remain open as usual. The NHAI assures that all this work will be finished before the monsoon season, ensuring that travelers do not encounter any hazards during the rainy period. This project is part of the development of a six-lane access-controlled highway from Ganeshpur to Asharodi on NH-72A under the Bharatmala Pariyojana.

The Ganeshpur-Dehradun section of the Delhi-Dehradun Expressway passes through a hilly area. Widening work on some sections of this stretch involved cutting through the mountains. Anticipating the risk of falling stones on the expressway, NHAI has already installed stone catchers at vulnerable locations.
