The iconic bridge once completed will be 30 meters higher than the Eiffel tower in Paris. To provide direct connectivity to Kashmir Valley, Railways started work on the world's highest bridge on the River Chenab in Jammu and Kashmir. It will provide direct access to the Kashmir valley. The iconic bridge will soar 359 meters above the bed of the River Chenab.
The bridge will link 111Kms between Katra and Banihal which is part of the Udhampur-Srinagar-Baramulla section of the Kashmir Railway project. The work has begun on installations of the main arch between two sides of the bridge and the main-arch has been launched.
The launch of the main arch will carry heavy segments from two ends of the bridge - Kauri end and Bakkal end. It would involve the world’s longest cable crane arrangement. The design of the bridge has been such that it can withstand an earthquake of magnitude 8 on the Richter scale and wind speed up to 260 kmph. Its lifespan is forecasted to be around 120 years. The 1.3 km long bridge will cost approximately Rs. 1,250 crore. The work is being executed by AFCONS through Konkan railways.
Consultants from India and abroad are involved at various stages of the project. Geophysical studies, seismic studies, and slope stability studies have been done in detail for durability and sustainability. The erection of the bridge is a major project by itself. Pylons were erected on either side of the river with two auxiliary self-propelled cable cranes to tow these auxiliary ropes. To support the partly finished arch parts, ropes were used. Stiff cliffs and heavy downstream in Chenab River is making the task all the more difficult.
This is for the first time that Railways viaduct was launched on the curve of 2.74 degrees. Three massive workshops have been built to undertake the fabrication work. The cable crane assembling unit including pylons at a span of 915 meters is the longest in the world. It is estimated that more than 1,300 workers and 300 engineers have been working round-the-clock to complete the bridge by May 2019.
