Mahatma Gandhi Setu (bridge) also called Gandhi Setu or Ganga Setu
in Patna is the Asia's 2nd longest river bridge and also longest cantilever
bridge of Asia. Length of Ganga Setu in
Patna is 5.75km and was inaugurated in 1982 by Indira Gandhi with the cost Rs
87.22 crore. It is also one of the tourist’s spots in Patna, Bihar. Mahatma
Gandhi Setu connects Patna in the south to Hajipur in the north of Bihar.
The bridge was approved by the Central Government in 1969
and built by Gammon India Limited over a period of ten years, from 1972 to 1982
with total expenditure of Rs 87.22 crore at that time. It was built to connect North Bihar with the
rest of Bihar and part of national highway 19 (NH19). . Before this bridge was
constructed, Rajendra Setu, opened in 1959, was the only link to North Bihar. The
Indian postal department issued a commemorative postage stamp on Landmark
Bridges of India: Mahatma Gandhi Setu of denomination 0500 Paise on 17 August
2007.
Before Mahatma Gandhi setu was built in Patna, people going
to north Bihar had to cross river Ganga by boat, a ship or a steamer. Other
option left with the people was to take a rail route which was very long. But
with inauguration of Gandhi Setu in Patna, this distance and pain of traveling
to north Bihar was greatly reduced. Its importance can be judged from the fact
that more than 40,000 vehicles pass this bridge everyday.
Mahatma Gandhi bridge in Patna constructed by Gammon India. The
bridge is considered to be an engineering marvel by many. The bridge has 45
spans of 121 meters each and one span of 65.53 meters on both sides. Cantilever
slabs with hinge bearings and box girders were used. This kind of technology
being used back in the 1970s truly makes this one of the best feats of Indian
engineering. The deck provides for a 7.5 metres (25 ft) wide two lane roadway
for IRC class 70 R loading with footpaths on either side. The cantilever
segmental construction method was adopted to construct this mega bridge. Each
span has two cantilever beams on both sides which are free to move at the ends.
It has two lanes one upstream and the other downstream each with a width of
around 6m. Both the lanes are also free from each other and are not connected
anywhere. It was constructed by using 3 meter pre-casted parts being joined at
both ends to complete the span. The Spans are connected by using a Protrusion
which is free to move longitudinally also along the river flow. In upwards and
downwards direction it is such that it allows vibration to transfer smoothly to
the next span while vehicular movement without much discreteness.
In recent times, the bridge has been witnessing major
traffic chaos and accidents due to exceeding number of vehicles passing over it
and regularly overloading the structure. Over 85,000 vehicles pass through
Gandhi Setu along with 12,000 pedestrians daily. The bridge is now in a
dilapidated condition owing to the massive overload caused by thousands of
vehicles passing by. Heavy exceeding traffic has caused a rise of pollution and
accidents. Chaos and congestion in the form of long traffic jams are a daily
affair. After 15 years of failed efforts made by the Ministry of Road Transport
and Highways, Prime Minister Narendra Modi inaugurated the repair work for the
bridge in January 2017. The existing superstructure shall be dismantled, and a
complete rehabilitation is to be done. Meanwhile, two pontoon bridges running
parallel to the setu have been constructed to facilitate decongestion of overflowing
traffic.
Patna Railway Station is at a distance of about 8 km from
the bridge. Patna Airport is at a distance of 14 km from the bridge.
