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 />
