Jubilee Railway Bridge
The “Jubilee” Railway Bridge was opened by Lord Dufferin, the Viceroy and Governor General of India, in 1887, during the Silver Jubilee year of the reign of Queen Victoria, the then Empress of India. It stands within a kilometre of the oldest Portuguese Church of Eastern India, and only two hundred metres from the classic Imambara (a Shia Muslim congregation hall and mosque) at Hooghly.

There is a belief that the railway engineers wanted to present their beloved Monarch a gift of unparalleled engineering accomplishment on the Golden Jubilee year of her reign as a befitting salute from her loyal subjects.

Jubilee Bridge has a cantilever truss structure constructed exclusively by riveting. It is designed for the end girders to rest on overhangs of the central girder.
Its unique construction also includes pendulum bearings, which perhaps are not seen in any other bridge in the country.
But being near the Bay of Bengal, the bridge substructure regularly suffers from the stresses emanating from repeated tidal movement.

The bridge abutments are made of brick masonry, whereas, the piers are partly made of steel.
Sampreeti Setu Bridge
In 1999, after 112 years, the need for replacement of the Jubilee Bridge was acutely felt by the Indian Railways. Therefore, during 1999-2000, a new double line bridge was sanctioned to be built. Named Sampreeti Setu, this bridge is located by the side of the old bridge. With a Double-D well foundation, it comprises of two end spans of 132.5 metres each and a central span of 150 metres.
Inspired by the Sydney Harbour Bridge, in Australia, Sampreeti Setu has been designed with a continuous steel bow-string superstructure, with open web girder of 417 metres length and height of 45 metres.
