The New Jubilee Bridge –<br />

Innovative Design by 3D<br />

Modelling<br />

A vital railway link, the bridge was originally constructed for a double<br />

line with 12-foot track centers. The advent of wider stocks and heavier<br />

axle loads caused it to be converted to a single-line gauntleted track<br />

bridge in 1910. The Jubilee Bridge is still operational, but has strict<br />

speed restrictions that hinder the smooth flow of rail traffic,<br />

including freight.<br />

A veiw of Jubilee Bridge<br />

THE Jubilee Bridge in Kolkata, India,<br />

spans the river Hooghly between the<br />

Bandel and Naihati railway stations. It<br />

was constructed in 1887, the year of the<br />

Golden Jubilee marking the 50th anniversary<br />

of Queen Victoria’s reign and hence<br />

was named so.<br />

Designed and built by Sir Bradford<br />

Leslie, the Jubilee Bridge is a bowstring<br />

bridge type with a central balance<br />

cantilever grade 360 feet long supported<br />

on two piers 120 feet apart. The<br />

suspended girders at each end measure<br />

420 feet.<br />

New Bridge<br />

India’s Eastern Railways planned a replacement<br />

bridge and in 1987 commissioned<br />

RITES Ltd. to carry out detailed<br />

studies and determine a location for the<br />

new bridge. RITES submitted its project<br />

report in 1990, in which the firm recommended<br />

the new bridge be located 25<br />

meters downstream from the existing<br />

bridge. RITES was subsequently engaged<br />

to carry out additional detailed<br />
