Name: Chenab Bridge
Type : Rail Bridge
Location: Kauri in Jammu's Reasi district in the state of Jammu & Kashmir
Completion Deadline: December 2009
Height above Chenab River: 359m
Length: 1315m
Cost: Rs600+ crores
Current highest bridge (surface-deck clearance): Royal Gorge Bridge,Colorado,USA-321m above Arkansas river. Its a pedestrian bridge but is also used by cars. Millau Viaduct in France is 270m above the Tarn river and 343m above land. It'll remain the tallest due to the height of the pylons.

The Chenab bridge is part of the Jammu-Udhampur-Srinagar-Baramulla railway route and will have the highest surface-deck clearance at 359m above the Chenab River.

thx for pics, plans, figures. Can you post also exact coordinates?
Anyway in 2009 it may be also arch bridge with 6th longest span in the world.

That's what counts to me.
My bad. I should have written that 343 is the highest point(top of pylon) in the Millau Bridge. The distance between the deck and the lowest point(tarn river) is 270m which is less than Royal Gorge bridge's clearance.

I looked around and couldn't find the exact coordinates. However, it's located 60kms North of a town called Katra.

Wow!!. awesome ain't it. Kashmir is going places these days. There is a massive Archeological Survey of India plan to restore Srinagar Jama Masjid to its old prestine glory too.

What kind of construction is it? It looks like steel. The design is very similar to the Colorado River Bridge under construction right now in front of Hoover Dam. That one is concrete and about 270 meters above the river.

It looks pretty awsome.
Though it doesn't looks that high, if i look at the impression, the Millau bridge looks higher. But maybe that's just a grand illusion.

yeah steel it is.

here's a pic of the approach viaduct u/c leading to the arch of the bridge -

lol, this bridge is sort of, but not as bad as, that other Mexican bridge.

To me, Millau still is the highest, it's actually got pillars down to the "lowest point"

There's a difference between being classified as "tallest" and "highest". Millau takes the cookie for being the tallest due to its piers but the deck of the bridge isn't as high above the lowest point on the ground as is the deck of this bridge u/c.

come on, it is NOT the tallest bridge either. There are more taller bridges than 359m are built or being built.

Bailing River Bridge in Guizhou, China, it is over 370m from surface of bridge to the river surface underneath. It is also world 16th longest suspension bridge in main span (1008m).









Beipan River Bridge in Guizhou, China, is also already built. Its surface to river surface is 404m!

That would be heighest bridge then (thus the distance between deck and (river)surface. Tallest would still be Milau because it's pillars are 343 meters.

Nice bridge though, reminds me of the classic bridges in the UK, US and France although this one is much taller.

And Sidu River Bridge (u/c) is even higher. The distance from bridge surface to the bottom of valley is 560m!

Sidu River Bridge is a suspension bridge with a total length of 1365m and the main span 900m. The tower in the Eshi side is 118.2m high and the Yichang side 113.6m high. From the top of the tower to the bottom of the valley, there is about 650m which makes it the highest bridge in the world. Main cables are supplied by SPCC in 2005.













Two pilot cables successfully launched by rockets in Hubei



Two pilot cables 980 meters long have been successfully fired into a canyon from the construction site of the Sidu River Bridge by two rockets in Hubei Province.

The surface of the Sidu River bridge, which is on the west side of the Shanghai-Chengdu Expressway in Hubei Province, is 560 meters away from the canyon. It is the world's highest bridge.

This new technology helps solve the worldwide difficulty of launching pilot cables into a canyon.

Launching pilot cables by rocket is a world first. The successful launch was conducted by People's Liberation Army and China Road & Bridge Corporation.

Plans to construct the bridge over the chenab river have been officially cancelled as it was discovered to be "infeasible"

From the Times of India Sept 12 2008

http://timesofindia.indiatimes.com/...t_bridge/articleshow/msid-3473521,curpg-1.cms


In a bid to undo a Himalayan blunder, the government has scrapped the four-year-old project of building the world's highest bridge on Chenab (359 metres), a crucial part of the first railway line to Kashmir. The delay in cancelling the bridge, which was supposed to be built for Rs 512 crore, may cost it dearly as the government is already facing claims of Rs 300 crore from an international consortium involved in the project.

The abandonment of the bridge follows a belated discovery that it is unfeasible as the gorge in a high-relief mountainous region is not stable enough to bear the load of the mega steel arch.

In a letter dated September 4, the railway board announced "all existing contracts" with Konkan Railway Corporation Limited (KRCL) for a 34-km stretch of the railway link between Jammu and Kashmir, which includes the construction of the Chenab mega arch bridge, have been "short closed" (meaning, terminated before completion of work).

As a corollary, the board's decision puts a stop to the sub-contract signed by KRCL in 2004 with the international consortium, Ultra-Afcons-VSL, to design and build the Chenab bridge within 30 months. Though the stipulated period for the execution of the project lapsed last year, the consortium is yet to build even the foundation in the mountain slope on either side of the river as Northern Railways, in view of the treacherous geological conditions, could not clear any of its plans for the bridge.

In a tacit reference to the claims of Rs 300 crore submitted by the consortium for the manpower and machinery idling at the site, the board said, "A proper record of material, unfinished work abandoned at the site shall be kept for examining legitimate claims."

The decision to scrap the bridge was taken by the board's member (engineering) S K Vij as a sequel to an order passed by him on July 14 suspending all works on the existing alignment of the entire 125 km track between Katra and Banihal skirting the mountains at altitudes ranging from 800 to 1,700 metres. The proposed alignment reduces the route length from 125 to 70 km as it's based on the new technology of tunnelling through mountains insulating the rail track from landslide-prone slopes.

It also offers the advantage of a double line even as it reduces the cost of the project: while the present alignment with a single tract is estimated to cost Rs 7,300 crore, the proposed one is calculated to incur an expenditure of Rs 6,500 crore over five years.

With the scrapping of the Chenab bridge in the existing alignment, the adoption of the modified alignment seems inevitable.
