    J-K Rail Project: Country’s First Cable-Stayed Rail Bridge In Reasi Completed

    Jammu, Apr 29: The work on the country’s first cable-stayed railway bridge at Anji Khad in Reasi district of Jammu and Kashmir has been completed, Railway Minister Ashwini Vaishnaw said.

    The completion of the bridge drew praise from Prime Minister Narendra Modi who is keenly monitoring the Udhampur-Srinagar-Baramulla Railway Link (USBRL), which will provide rail connectivity between the Kashmir Valley and the rest of the country.

    “In 11 months, India’s first cable-stayed rail bridge (Anji Khad) is ready…,” Railway Minister Ashwini Vaishnaw tweeted on Friday, sharing a video of the completed bridge. The total length of the cable strand used in the bridge is 653 km.

    Reacting to Vaishnaw’s tweet, the prime minister wrote “excellent”.

    The completion of Anji Khad bridge, having a single pylon with a height of 331 metres above the river bed on Udhampur-Srinagar-Baramulla Rail Link (USBRL), is yet another major breakthrough achieved by the Indian Railways, which is expecting to complete the Rs 37,000 crore project by the end of this year.

    Minister of State for Railways Darshana Vikram Jardosh, who recently inspected the USBRL project by visiting various key locations including Anji Khad bridge and the nearby iconic Chenab bridge, termed the completion of the country’s first cable-stayed bridge as “another milestone” despite difficult geographic conditions.

    “I visited the bridge site and congratulated everyone for successfully installing all 96 cables of the bridge in a record time of 11 months. This asymmetrical cable-stayed bridge crosses the deep gorges of Anji river, a tributary of river Chenab,” she said.

    Jardosh said the bridge connects tunnel T2 on the Katra side and Tunnel T3 on the Reasi side.

    “It has been the PM’s vision to make Indian railways the best in the world. Overcoming geographic and climatic challenges, our engineers and railway officials have conquered the invincible,” the minister said.

    Described as a “true engineering marvel”, the bridge has 48 cables each on lateral and central spans with work on its pylon started in 2017, officials said, adding the pylon is standing 191 metre from its foundation level.

    They said It is the second highest railway bridge after the iconic arch bridge over Chenab at Kauri, which is the highest railway bridge in the world being 359 metres above the river bed level — 35 metres higher than the iconic Eiffel tower in Paris.

    Anji Khad bridge has a total length of 473.25 metres, while the length of the viaduct is 120 metres. The central embankment has a length of 94.25 meters, the officials said.

    They said the bridge has been designed to handle heavy storms of strong winds and even explosions.

    In October 2016, the Railways decided to build a cable-stayed bridge at Anji Khad after the plan to build an arch bridge similar to Chenab bridge was abandoned due to vulnerability of the structure, primarily due to concerns over geological stability of the region.

    The Railway Ministry sanctioned the construction of the railway line from Udhampur to Baramulla via Srinagar in phases — 25-km Udhampur to Katra in 1994, 118-km Qazigund to Baramulla and 129-km Katra to Qazigund in 1999.

    In view of the importance of the USBRL in providing seamless and hassle-free connectivity to Kashmir, the 272-km-long rail link was declared as a “National Project” in 2002.

    Out of the total 272-km USBRL project, 161-km was commissioned in phases with first phase 118-km Qazigund-Baramulla section commissioned in October 2009, followed by 18-km Banihal-Qazigund in June 2013 and 25-km Udhampur-Katra in July 2014. The work on 111-km Katra-Banihal stretch is going on.–(PTI)

  • India’s first cable-stayed rail bridge on Anji river in J-K near completion

    Jammu: The first cable-stayed railway bridge of India is expected to be ready by May this year on the Anji river in Jammu and Kashmir, Northern Railway officials said.

    Once ready, trains will run at a speed of 100 kmph (Km per hour) on the bridge being constructed around 80 km away from Jammu, they said.

    Anji bridge between Katra and Reasi stations falls in the Reasi district of the union territory of Jammu and Kashmir. The upcoming structure is part of the ambitious Udhampur-Srinagar-Baramulla-Rail Link (USBRL) project that railway minister Ashwini Vaishnav had announced to be completed next year.

    According to officials, the last deck portion of Anji bridge which is designed to withstand the wind at the speed of 213 kmph is expected to be completed in May this year as six more segments of the bridge are yet to be launched.

    “We have already completed 41 out of 47 segments. We are hopeful that the remaining ones would be completed by April-end or in the first week of May,” the official said.

    He said the central span of the cable-stayed bridge is 290 metres and only a 52.5-metre portion remains to be completed.

    “The speed of trains will be 100 kmph on this bridge which is the speed for the entire project. However, the trains will be stopped if the wind speed goes beyond 90 kmph,” the senior official said.

    Currently, trains operate between Udhampur to Katra section. The project work on the 111-km Katra to Banihal line is currently underway and 52 km of this section including the bridges on Anji and Chenab are being built by the Konkan Railway. Banihal and Baramulla are also connected by trains.

    Once completed, the USBRL project will connect the Kashmir Valley to the Indian rail network.

    Anji bridge is an “asymmetrical” bridge erected on a single pylon and it has tunnels on both ends. A tunnel on the Katra end is 5 km in length while another on the Kashmir end is 3 km in length. A track is laid in both tunnels, according to officials.

    The cable-stayed portion of Anji bridge is 472.25 metres while the total length of the bridge is 725.5 metres, which is divided into four parts including an embankment, officials said.

    The deck level of the 193-metre tall bridge from the foundation is 51 meters, while the invested Y-shaped pylon above the deck level is 142 meters, the officials said, adding that the bridge work started in 2017.

    However, the main cable-stayed bridge work started in April 2018, after the completion of the approach portion, an official said.

    The official said the bridge has the codal life of 120 years and it will be able to bear the explosion of 40-kg of explosive material. The bridge will also have an integrated monitoring system with numerous sensors installed at various locations.

    “Site-specific earthquake parameters studies were carried out by the Department of Earthquake Engineering, Indian Institute of Technology, Roorkee, to define the seismo-tectonic framework for the region,” the officer said.

    According to railway officials, the bridge is located in the young-fold mountains of the Himalayas having extremely complex, fragile and daunting geological features in the form of faults, folds and thrusts. Besides seismic proneness of the region, detailed site-specific investigations were carried out by IIT, Roorkee and IIT, Delhi, they added.
