is
a double-decked steel truss
bridge which
runs
across
the Yamuna
river in
the
southern
part
of
the
city.The
bridge
runs
North-South
across
the
Yamuna

It

capability
of
roadways
and
railways
simultaneously.
Its
upper

has
a
two
lane
railway
line
which
connects
Naini
Junction
railway
station
to
Allahabad
Junction
railway
station,
while
the
lower
deck
has
successfully
been
facilitating
roadway
services
since
1927.
The
bridge
opened
in
1865
to
provide
a
through
line
from Howrah (on
the
right
bank
of
the
Hoogly
River
facing Calcutta)
to Agra (on
the
left
bank
of
the
Jamuna
River
facing Agra,
a
line
length
of
1017
miles(1630km) [3].
The
location
of
the
bridge
between
Naini
and
Allahabad
had
been
decided
as
early
as
1855.
The
actual
work
began
in
1859
and
the
bridge
was
opened
for
public
on
August
15,
1865.
By
then,
rail
lines
on
both
sides
of
the
bridge
to Delhi and Howrah was
almost
complete.
The
length
of
the
bridge
is
3,150
feet.
It
comprises
14
spans
of
200
feet
and
two

60
feet.
The
bridge
has
a
railway
line
on
the
top
and
a
roadway
beneath.
It
was
designed
by
engineer Alexander
Meadows
Rendel.

up
to
42
feet

is
58.75
feet.
The

is
4,300
tons.
It
is
estimated
that
about
2.5
million
cubic
feet
of
masonry
and
brick
work
was
used
in
it.
The
stone
for
the
bridge
construction
was
from
the Purtabore
Stone
Quarry where
a
tramway
carried
the
stone
to
the
bank
of
the
River
Jamuna
for
shipment
to
the
site [5]..
In
1927-29,
the
old
girders
were
replaced
by
new
ones
and
the
lower
deck
was
added
for
roadway
services.
The
upper

being
the
two
lane
railway
line
which

Junction
railway
station
to
