History of construction

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 navigabilityproblems in the rivers. The need for a bridge over the river Jamuna was felt, especially by the people living in north-western Bangladesh, for a long time. This perceived need did not go unnoticed by the policy makers. The people and successive governments always longed to bridge the mighty Jamuna and thereby integrate the communication systems of the region. Popular leader Maulana Abdul Hamid Khan Bhashani first raised the demand for construction of theJamuna Bridge at a political level in 1949. In the 1954 provincial elections of East Pakistan, the 21-point manifesto of the united front contained a demand for the bridge. On January 6, 1964, Mohammad Saifur Rahman, a member from Rangpur in the Provincial Assembly inquired about government’s intentions with regard to the construction of a bridge over the Jamuna. On July 11, 1966, Shamsul Haque, another member from Rangpur in the same Assembly, moved a resolution for the construction of the bridge and the house adopted it unanimously.
Accordingly, a preliminary feasibility study was carried out in 1969 by Freeman Fox and Partners of UK. They recommended a rail-cum-road bridge near Sirajganj with an estimated cost of $175 million. The estimates were preliminary in nature and a more detailed study was recommended. On the other hand, in his address to the nation over radio and television on the eve of general election in Pakistan in 1970, the Awami League leader Sheikh Mujibur Rahmanmentioned the construction of Jamuna Bridge as an election pledge of his party. But all efforts were interrupted due to political unrest and liberation war.
After Bangladesh attained independence in 1971, the new government publicly stated its intention in 1972 to construct a bridge over the Jamuna and budgetary provisions were kept for the purpose in the 1972-73 budget. On being invited by the Bangladesh government, the Japan International Cooperation Agency (JICA) funded a feasibility study through Nippon Koei Co. Ltd. in 1973 on the construction of a road-cum-rail bridge over the Jamuna.
The JICA study, completed in 1976, concluded that the Jamuna project would cost $683 million with an economic rate of return (ERR) of only 2.6%. Considering that the project is not technically and economically viable, the government had abandoned the project. The government had, however, revived it later in 1982 and commissioned a new study to determine the feasibility of transferring natural gas to western parts of the country across the Jamuna. The study concluded that an independent gas connector was not economically viable. However, the consultants made an assessment of the engineering feasibility and cost of a combined road-cum-gas transmission bridge, which introduced the concept of a multipurpose bridge. It was estimated that a 12-km long bridge with three road lanes would cost $420 million. Upon consideration of the report, the cabinet made a decision to take immediate steps in pursuit of the project.
The Jamuna Multipurpose Bridge Authority (JMBA) was set up by an ordinance promulgated by the then President Hussain Muhammad Ershad on July 3, 1985 to implement the project. For mobilisation of domestic resources, another ordinance was promulgated by which a Jamuna Bridge surcharge and levy were introduced. A total of Tk 5.08 billion was mobilised in the process till its abolition.
In 1986, phase-I feasibility study for the bridge was carried out when the site between Sirajganj and Bhuapur (Tangail) was found to be the best. Between 1987 and 1989, the phase-II feasibility study was carried out when a road-cum-rail-cum-power bridge was found both economically and technically viable. Funding arrangements for the bridge were finally made with IDA, ADB and JBIC (formerly known as OECF) of Japan by the government of Bangladesh in 1992. Tenders were invited through international bidding for construction contracts in 1993. Contracts for the bridge, river training work and two approach roads were awarded in March 1994. The foundation stone of the bridge was laid on April 10, 1994. Physical implementation of the project commenced on October 15, 1994, and all the components except gas transmission line were completed by June 1998. The bridge was opened for traffic on June 23, 1998.
Jamuna Multipurpose Bridge was constructed at a cost of $62 million. The cost of construction was shared by IDA, ADB, OECF of Japan, and the government of Bangladesh. Of the total, IDA, ADBand OECF supplied 22% each, and the remaining 34% was borne by Bangladesh. The components of the project’s cost were as per given pie chart:

The main bridge is 4.8 km long with 47 main spans of approximately 100 metres and 2 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 crossing has been 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 located 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 located 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).
Considering the fact that the width of the main channel does not exceed 3.5 km, and after making allowances for floods, a bridge length of 5 km was considered adequate. In October 1995, one year after the commencement of physical work of the bridge, a bridge length of 4.8 km, instead of a flood-width of the river at 14 km, was finalised. This narrowing was essential to keep the overall project cost within economic viability. It has, however, required considerable river training work to keep the river under the bridge.
