The largest of all indian's railway bridges is the
Chenab Bridge, located on the
Jammu–Baramulla line that connects the
Jammu region and the
Kashmir Valley, which turned out to be the most expensive line of Indian's railway network. The Chenab Bridge was the highest arch bridge in the world when opening in 2022 with a deck 322 m (1,056 ft) above the
Chenab River, it's still the highest railway bridge on earth nowadays.[41][42]
Extradosed bridges have experienced remarkable growth in India since the 2010s with a large number of multi-span bridges built on rivers such as the
Ganges, which has significant widths in certain places. Their advantages are as follows:
They allow longer spans than conventional
beam bridges and therefore a reduced number of
foundations.
The thickness of the deck is considerably reduced (the Arrah–Chhapra bridge deck is 3.4 m (11 ft) thick), thereby minimizing the amount of concrete.
They can be made up of
precast segments even for medium spans and then be erected much more quickly and easily than the typical in-situ concrete construction.
A more elegant aesthetic appearance than conventional beam bridges.[43]
The first major extradosed bridge built in India is the
Second Vivekananda Bridge between
Howrah and
Kolkata. It has 8 pylons and a suspended length of 880 m (2,890 ft), which was among the longest in its category at the time. Additionally it had one of the largest numbers of spans at the time. Another main feature of the bridge is its 29 m (95 ft) width with 6 road lanes for a single plane axial suspension.[44]
The
Arrah–Chhapra Bridge held the record for the longest total extradosed span length in the world when it was inaugurated in 2017, with 16 pylons and 1,920 m (6,300 ft), surpassing the well-known
Twinkle Ibigawa Bridge [
ja] in
Japan.[43] This record will be largely beaten by the new
Kacchi Dargah–Bidupur Bridge under construction with 66 pylons and an extradose length of 9,750 m (31,990 ft).[45]
The
Rajendra Setu was the first rail-cum-road bridge in independent India on the river
Ganga, one of the major rivers in the country.
This table presents the structures with spans greater than 120 metres (390 ft) (non-exhaustive list).
^According to the statement of residents/users involved in the maintenance the bridge, it is estimated to be 200 years old.[1]
^This bridge is qualified as the oldest railway bridge in the world because it was built in 1735, before the very first railway lines, but the tracks were only installed in 1899 and the trains circulated on the bridge from 1092 to 2007.[21]
^The
Yuanjiang Railway Bridge in
China, completed in 2022, has the highest railway bridge pier in the world with 154 m (505 ft) from foundation to cap.[38]

^The given span arrangement is always the cantilevered arrangement, i.e. 420, 360 and 420 feet (130, 110 and 130 m) spans with a 120 feet (37 m) part between the two piers in the Hooghly River.[93][94] The clear span arrangement is then (165 m).
^Bogibeel Bridge is the longest rail-cum-road bridge in India, measuring 4.942 kilometres (3.071 mi) over the Brahmaputra river.[119] This length only takes into account the main truss bridge with the common road and rail part, the overall length of the road part including north and south approach viaducts is 6.610 kilometres (4.107 mi).[120]
^Due to structural failures, the bridge initially built as a balanced cantilever rigid frame had to be rebuilt. Box girders have been fully removed and a truss structure was installed in its place in 2022.[134]
