Dreamed Padma Bridge will be open of vehicular movement soon as the work of all 42 pillars has completed. Meanwhile, 27 spans have been installed out of 41 so far. The rest 14 spans are expected to installed by August.

The welding of the upper part of the 42nd pillar of Padma Bridge began on Tuesday. Padma Bridge engineers said the work would be completed by evening. They said the pillar will be in strong shape within the next three days and it will able to take full load by the month.

With the launch of the bridge, there will be a radical change in the communication system of the capital with the southwest 21 districts of the country. This will increase the gross domestic product growth (GDP) by 1 to 1.5 per cent. The poverty rate will decrease by .84 per cent. Garments and other factories will be built on the outskirts of Padma.

The work of Padma Bridge started four years ago. The project overcomes the biggest challenge through finishing the work of 42nd pillar. Occasionally the work has been delayed for over a year due to the complexity of the pillars.

China Major Bridge Engineering Company said that 39 spans out of 41 had come to Mawa and the work of rest two pillars is going on in China. Already 27 spans have been installed and 4050 kilometres of Padma bridge is visible now. Then the whole bridge will be visible together. The remaining two-pillar will left China for Bangladesh by April 20. 

A total, 41 spans will be installed on 42 pillars of 6.15km long Padma Bridge. The distance from one pole to another is about 150 meters. Each pillar is capable of carrying 50,000 tonnes of load.

Padma Bridge engineers said that they have to suffer much to install 22 pillars at the middle river and Mawa ends.

They also said that finally a method was applied so that artificial processes along the river bottom could be replaced by creating new soil and making poles. Success in applying this particular 'screen grouting' method they got success. 

Padmatsu International Expert Panel Chief Professor Dr Jamilur Reza Chowdhury said the special chemical was sent to the bottom of the river through a hole in a pipe to strengthen the soil quality and then the pillars were formed.

He said that the soil level found under the river to start work was not suitable for pillars. Later, the river's soil quality has to be changed by driving. This is the first time that a bridge has been constructed in Bangladesh. Which is unprecedented in the world.

The project concerned said that 11 pillars have been developed through this process and the latest one is 42nd pillar. 

It is to be noted that on 30th September 2007, the first span has been set on pillar number 37 and 38. Then the second span on the 38th and 39th pillars on 28th January, the third span on March 11, on the 39th and 40th pillars, the fourth span on the 40th and the 41st pillars on 31st May and the latest fifth span has been installed on41st   and 42nd pillars on 29th June last year.
