World's highest railway bridge,being built in the
Himalayas
*********************************************************
Indian engineers are toiling in the Himalayas to build the world's
highest railway bridge which is expected to be 35 meters taller than the Eiffel
Tower when completed by 2016.The arch-shaped steel structure is being
constructed over the Chenab River to link sections of the spectacular
mountainous region of India's northern Jammu and Kashmir state. The bridge is
expected to be 359 meters (1,177 feet) high when completed, surpassing the
world's current tallest railway bridge over the Beipanjiang River in China's
Guizhou province, which stands at 275 meters high. And a span width of 236 meters
was built in 2001 with the construction of the Shuibai Railway.
It
is an engineering marvel. We hope to get this bridge ready by December 2016, a
senior Indian Railways official told. The design would ensure that it
withstands seismic activities and high wind speeds. Work on the bridge started
in 2002 but safety and feasibility concerns, including the area's strong winds,
saw the project halted in 2008 before being green-lighted again two years later.
The estimated cost of the project, which is being handled by Konkan Railway
Corporation, a subsidiary of state-owned Indian Railways, is $92 million.
The bridge will
connect Baramulla to Jammu in the Himalayan state with a travel time of
six-and-a-half hours, almost half the time it currently takes. The main arch is
being erected using two cable cranes attached on either side of the river which
are secured on enormous steel pylons, according to engineers of the project. 1,315-metre
long bridge will use up to 25,000 tons of steel with some material being transported by helicopters due to the tough
terrain. One of the
