Work on the Kachchi Dargah-Bidupur six-lane bridge project over the Ganga has picked up pace, with concrete-laying in a well foundation starting on Wednesday on the Raghopur side.

Well foundation, a road construction department engineer explained, is the sub-structure that is like the foundation of a bridge.

"Concreting one well foundation takes six months, and 67 well foundations would be constructed," the road construction department engineer explained.

Work on a new well foundation will start every 15 days, and each well foundation will cost Rs 12 crore.

The bridge will have its northern end near Bidupur in Vaishali district and southern end at Kachchi Dargah in Patna district, and when complete will be a key link between north Bihar and the rest of the state.

The Korean firm Daewoo Engineering and Construction Company limited, in a joint venture with L&T India is executing the Rs 4,988.4crore bridge project which when complete will be 22.76km long including approach roads. The Asian Development Bank has given loan of Rs 3,000 crore and the state government will bear the rest amount is given by state government.

"Every span of the bridge would be 150-metre long and navigable. Every span would be built with the 10-metre-height flood level deck. It means even a big ship can pass under this bridge," the engineer said.

The executing agency is equipped with 10,000 metric tonnes of stone, 5,000 metric tonnes of sand, 6,500 bags of cement and adequate manpower. Work will continue through the rainy season to meat the completion deadline of January 2020.

To continue the work in rainy season, two barges have been arranged to transport material from the Patna side. One barge can take the load of at least five trucks. "We have completed a 4km approach road on the Raghopur side for taking the machinery to the construction site," said an engineer working on the project.

The state acquired land under the urgency clause for the project.

In first nine months of the beginning of the project only 10 per cent of the land was acquired. After the urgency clause was invoked, the state government acquired 80 per cent of land within four months.

The bridge will have 1,002 pile foundations, 67 well foundations, 945 viaducts, 16 steel girders and 70 concrete girders.
