The Anji Khad Rail Bridge, situated in the Reasi district of Jammu and Kashmir, stands as a testament to India’s engineering prowess. This landmark structure is India’s first cable-stayed rail bridge and forms a crucial part of the ambitious Udhampur-Srinagar-Baramulla Rail Link (USBRL) Project. The project is envisioned to enhance connectivity to the Kashmir Valley, significantly boosting economic development and tourism in the region.
Overview of the Anji Khad Bridge
Spanning a total length of 725.5 meters, the Anji Khad Bridge is a striking example of modern engineering. Its single main pylon, rising to 193 meters above the foundation, makes it an architectural marvel and an iconic addition to India’s railway infrastructure. The bridge connects Katra and Reasi, providing a more accessible and seamless travel experience for locals and visitors.
Engineering Challenges and Innovative Solutions
Constructing the bridge in the Reasi district was no easy feat. The region’s challenging terrain, characterized by geological complexities such as faults, folds, and seismic activity, demanded innovative solutions. Leading institutions like IIT Roorkee and IIT Delhi conducted extensive investigations to ensure structural safety. A hybrid foundation was employed at the Katra end to stabilize the slopes, enabling the bridge to withstand the demanding conditions.
Structural Specifications
The Anji Khad Rail Bridge comprises four main sections, each showcasing advanced design and engineering:
- Ancillary viaduct (120 meters) on the Reasi side.
- Approach bridge (38 meters) on the Katra end.
- Cable-stayed section (473.25 meters), forming the heart of the bridge.
- Central embankment (94.25 meters).
The bridge features a 15-meter-wide deck, accommodating a single railway line, a service road, and footpaths, ensuring both functionality and efficiency.
Advanced Construction Techniques
Cutting-edge techniques were employed to overcome construction challenges and enhance efficiency. The use of DOKA Jump form shuttering and pump concreting systems reduced construction time by approximately 30%. A state-of-the-art tower crane, imported from Spain, was instrumental in completing work at heights of up to 193 meters. These methods underscore India’s capability to adopt global best practices in infrastructure projects.
Safety and Monitoring Systems
Safety has been a cornerstone of the Anji Khad Bridge’s design. An integrated monitoring system with numerous sensors is embedded throughout the structure to track its health and ensure long-term safety. The bridge can withstand wind speeds of up to 213 km/h, further demonstrating its robust design against extreme weather conditions.
Key Highlights
- Main pylon height: 331 meters above the riverbed.
- Design speed: 100 km/h.
- Micro piles: Constructed to a depth of 40 meters for added stability.
- The project was executed with guidance from ITALFERR, part of Ferrovie dello Stato Italiane, a globally renowned railway engineering firm.
Future Impact on Connectivity
The Anji Khad Rail Bridge is set to revolutionize connectivity in Jammu and Kashmir. By linking the Kashmir Valley to the Indian Railways network, it will significantly reduce travel time, improve accessibility, and serve as a catalyst for the region’s economic and tourism development. The bridge is more than just an infrastructure project; it symbolizes progress and integration for the region.
About the USBRL Project
The Udhampur-Srinagar-Baramulla Rail Link (USBRL) Project, declared a National Project in 2002, is a 272-km-long rail corridor designed to integrate Kashmir with the rest of India. Key features of the project include:
- Chenab Bridge: The world’s highest railway bridge, standing at 1,315 meters in length.
- T-49 Tunnel: India’s longest transportation tunnel, stretching 12.75 km.
By combining world-class engineering with visionary goals, the USBRL Project is reshaping the connectivity and future of Jammu and Kashmir.
A Landmark in Indian Railways
The completion of the Anji Khad Rail Bridge is a historic moment for Indian Railways. It not only demonstrates the country’s growing expertise in handling complex engineering projects but also reflects the government’s commitment to enhancing infrastructure in remote and challenging regions. The bridge stands as a beacon of progress, promising a brighter and more connected future for Jammu and Kashmir.
