Bangabandhu
Bridge,
also
known
as
the Jamuna
Multi-purpose
Bridge (Bengali: যমুনা
বহুমুখী
সেতু Jomuna
Bohumukhi
Setu)
is
a
bridge
opened
in Bangladesh in
June
1998.
It
connects Bhuapur on
the Jamuna
River's
east
bank
to Sirajganj on
its
west
bank.
It
was
the
11th longest
bridge
in
the
world when
constructed
in
1998
and
at
present
is
the
6th
longest
bridge
in South
Asia.
The
Jamuna
River,
which
it
spans,
is
one
of
the
three
major
rivers
of
Bangladesh,
and
is
fifth
largest
in
the
world
in
discharge
volume.
The
river Jamuna (Brahmaputra),
along
with
the
lower
stretch
of
the Padma (Ganges)
divides
Bangladesh
into
nearly
two
equal
halves.
Until
now
all
road
and
rail
communication
between
the
two
parts
of
the
country
has
had
to
rely
on
time-consuming ferry services
that
were
often
disrupted
because
of navigability problems.
The
need
for
a
bridge
over
the
Jamuna
River
was
felt,
especially
by
the
people
living
in
northwestern
Bangladesh,
for
a
long
time.
This
perceived
need
did
not
go
unnoticed
by
the
policy
makers.
Jamuna
Multipurpose
Bridge
was
constructed
by
Hyundai
Heavy
Industries[citation
needed] at
a
cost
of
$696
million. But
the
whole
bridge
project
costed
1.24
billion
dollar
for
unknown
reason. The
cost
was
shared
by IDA, ADB, OECD,
and
the
government
of
Bangladesh.
Of
the
total,
IDA, ADB and OECD supplied
$200
million
each
through
a
loan
with
1%
nominal
interest, and
the
remaining
$96
million
was
borne
by
Bangladesh.
The
main
bridge
is
4.98
kilometres
(3.09 mi)
long
with
49
main spans of
approximately
99
metres
and
two
end spans of
approximately
65
metres.
Connected
to
the
bridge
are
east
and
west approach viaducts each
with
12
spans
of
10
metre
length
and transition
spans of
8
metres.
The
total
width
of
the bridge
deck is
18.5
metres.
The river
crossing was
designed
to
carry
a
dual
two-lane carriageway,
a dual
gauge (broad and metre) railway,
a
high
voltage
(230
kV) electrical
interconnector, telecommunication cables and
a
750 mm
diameter
high
pressure natural
gas pipeline.
The carriageways are
6.315
metres
wide
separated
by
a
0.57
metre
width
central
barrier;
the
rail
track
is
along
the
north
side
of
the
deck.
On
the
main
bridge,
electrical
interconnector pylons are
positioned
on
brackets
cantilevered
from
the
north
side
of
the
deck.
Telecommunication
ducts
run
through
the
box
girder
deck
and
the
gas
pipeline
is
under
the
south
cantilever
of
the
box
section.
The
bridge
has
been
built
by Hyundai
Engineering
and
Construction (Korea)
as
a
'design
and
build'
contract.
TY
Lin
Assoc.
of
San
Francisco
carried
out
the
design
as
a
sub-contractor
for
Hyundai.
The approach
roads were
constructed
by
Samwhan
Corporation
(Korea).
