Pir Panjal Railway Tunnel, Jammu & Kashmir
Popularly called the Banihal Railway Tunnel, the Pir Panjal Railway Tunnel stretches 11.2 km through the Pir Panjal range of the Himalayas at an altitude of 1,440 feet. It is India’s longest and Asia’s second-longest railway tunnel, linking Banihal’s Bichleri Valley with Qazigund, and serving as a crucial part of the Udhampur–Baramulla route.
New Pamban Bridge, Tamil Nadu
The new Pamban Bridge is India's first vertical-lift railway sea bridge, inaugurated in April 2025 to replace the century-old original structure. The 2.07 km long bridge connects the mainland town of Mandapam with Rameswaram on Pamban Island in Tamil Nadu.
Dhola-Sadiya Bridge, Assam
The Dhola-Sadiya Bridge, officially named the Bhupen Hazarika Setu, is India’s longest water bridge at 9.15 km. Built across the Lohit River in Assam, it was inaugurated on May 26, 2017. The bridge strengthens connectivity between Assam and Arunachal Pradesh while also boosting strategic mobility and regional security.
