The Anji Khad bridge is a cable-stayed bridge connecting the Katra and Reasi sections of the Udhampur-Srinagar-Baramulla-Rail-Link (USBRL) in the Jammu Division of Jammu and Kashmir, India.
The bridge lies south of the Chenab Bridge, near Reasi, where the railway line crosses the deep chasm ('Khad' in Hindi) of the Anji River. It is India's first cable-stayed railway bridge. It has been built by Hindustan Construction Company, and is widely regarded as an engineering marvel of modern India.
The Anji Khad bridge was initially proposed to be an arch bridge. It was designed as a long steel arches span bridge. Its total length was to be 473 m (1,552 ft), with a main arch span of 265 m (869 ft), and a deck height of 189 m (620 ft). Quality aspects, construction standards, indigenous materials, and the painting scheme were proposed to be similar to the Chenab Bridge. Later, a committee headed by a former railway board chairman recommended that the location was not suitable for an arch bridge. In particular, the unstable geology of the Himalayan mountains combined with the steepness of the sides of the gorge made an arch bridge impractical. [2]
In October 2016, Indian Railways decided to build a cable-stayed bridge at Anji Khad, [3] with a striking asymmetrical design supported by 96 cables anchored to a single pylon on the Reasi side, of height 193 m from its foundation. [4] The initial cost of the project was set at ₹458 crore. As per the design, the bridge connects tunnels T34 and T35 on the Katra and Reasi sides respectively. It has a 290 meter main span at a height of 331 m above the riverbed. [5] The main section has a length 473.25 meters out of a total length of over 1,300 meters, with a 120 meter long viaduct.
A cable-stayed bridge has one or more towers, from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.
Katra is a city and Tehsil in the Reasi district of the Indian union territory of Jammu and Kashmir. It is situated at the foot of the Trikuta Mountains, where the shrine of Vaishno Devi is located. Katra is located 24 km (15 mi) from the town of Reasi, 42 km (26 mi) from the city of Jammu and around 685 km (426 mi) north of the national capital New Delhi and is the base for pilgrims visiting the Mata Vaishno Devi Temple.
The Mountain railways of India are the railway lines that were built in the mountainous regions of India. The term mainly includes the narrow-gauge railways in these regions but may also include some broad-gauge railways.
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.
The Jammu–Baramulla line is a railway track between the towns of Jammu and Baramulla in Jammu and Kashmir, India. The 338 km railway track will connect the Kashmir Valley with Jammu Tawi railway station and thence to the rest of India. It comes under the jurisdiction of the Jammu Railway Division of Indian Railways's Northern zone. Part of this railway route from Udhampur to Baramulla is known as Udhampur-Srinagar-Baramula Rail Link (USBRL). The 359 m (1,178 ft) high Chenab Bridge lies on this line, which is the highest railway bridge in the world. The total project cost in 2022 was INR28,000 crore. Construction of the route faced natural challenges including major earthquake zones, extreme temperatures and inhospitable terrain.
Reasi is a town and a notified area committee and tehsil in Reasi district of the Indian union territory of Jammu and Kashmir. Situated on the bank of River Chenab, It is the headquarters of the Reasi district. In the eighth century, Reasi was a part of the Bhimgarh state established by Rajput king Bhim Dev Rasyal. The name Reasi is derived from the town's old name, "Rasyal".
Salal Dam, also known as Salal Hydroelectric Power Station, is a run-of-the-river hydropower project on the Chenab River in the Reasi district of the Jammu and Kashmir. It was the first hydropower project built by India in Jammu and Kashmir under the Indus Water Treaty regime. After having reached a bilateral agreement with Pakistan in 1978, with significant concessions made to Pakistan in the design of the dam, reducing its height, eliminating operating pool, and plugging the under-sluices meant for sediment management, India completed the project in 1987. The concessions made in the interest of bilateralism damaged the long-term sustainability of the dam, which silted up in five years. It currently runs at 57% capacity factor. Its long-term future is uncertain.
Reasi district is an administrative district in the Jammu division of Indian state of Jammu and Kashmir in the Jammu region. The Reasi district is bordered by Udhampur district and Ramban district in the east, Jammu district in the south, Rajouri district in the west and by Kulgam district on the north. The Reasi and Rajouri tehsils formed a joint district called the "Reasi district" at the time of the princely state's accession to India in 1947. As part of the reorganisation, the two tehsils were separated and Reasi was merged with the Udhampur district. It again became a separate district in 2006.
The Chenab Rail Bridge, is a steel and concrete arch bridge carrying a single-track railway line, located between Bakkal and Kauri in the Reasi district of the Jammu Division of Jammu and Kashmir, India. The bridge spans the Chenab River at a height of 359 m (1,178 ft) above the river, making it the world's highest rail bridge and the world's highest arch bridge. The bridge was fully completed and was inaugurated in August 2022. It is built between the Sangaldan Railway Station and the Reasi Railway Station.
Vidyasagar Setu, also known as the Second Hooghly Bridge, is an 822.96-metre-long (2,700 ft) cable-stayed six-laned toll bridge over the Hooghly River in West Bengal, India, linking the cities of Kolkata and Howrah. Opened in 1992, Vidyasagar Setu was the first and longest cable-stayed bridge in India at the time of its inauguration. It was the second bridge to be built across the Hooghly River in Kolkata metropolitan region and was named after the education reformer Pandit Ishwar Chandra Vidyasagar. The project had a cost of ₹388 crore to build. The project was a joint effort between the public and private sectors, under the control of the Hooghly River Bridge Commissioners (HRBC).

Chenab Valley is a loosely-defined controversial term sometimes used to refer to parts of the Jammu Division of Jammu and Kashmir, India. The term is used to refer to the present-day districts of Doda, Kishtwar, Ramban, and, at times, Reasi and parts of Udhampur and Kathua. The first three districts used to be part of a single former district called Doda, which was created in 1948 out of the eastern parts of Udhampur district of the princely state of Jammu and Kashmir, and are sometimes collectively referred to as the Doda belt. The term is seen to be aimed at a communal break-up of the Jammu Division and iteration of Kashmiri Muslim irredentism.
