"The joint venture received the contract for Rs 987 crore in November 2011 to construct 36 spans or girders. Now the design has been modified with requirement of 41 spans... The total cost to construct the entire superstructure will now be around Rs 1,300 crore," HCC Project In-Charge (Bogibeel Bridge) Santosh Kumar Misra said.
Hindustan Construction Company owns 51 per cent stake in the JV, where Germany-based DSD Brouckenbau has 20 per cent and VNR Infrastructure has 29 per cent holdings, building the girders or superstructure.
"The earlier timeline given to us for opening the entire project to public was November 2015, but it has been delayed due to various factors. Now we will complete our work by December 2016 and the bridge will be opened for public by June 2017," Misra said.
The Northeast Frontier Railway project, which was first initiated during the tenure of former Prime Minister HD Deve Gowda in 1997, has missed several deadlines of completion since then.

"The first span was launched in April 2014 and so far we have rolled out 10 units on the river. Another 10 spans are being prepared to launch by this month. We are now planning to deliver two spans every month," he added.
To expedite the work further, HCC is planning to add 150-200 more workers to its current strength of around 2,500 people at the southern bank of Brahmaputra, which has rication, assembly and launching facilities, Misra said.
Currently, the 5.6 km long Bandra-Worli sea link, also constructed by HCC, is the longest bridge but offering only road network in Mumbai.
The total cost of Bogibeel project has escalated drastically over the years and is now likely to touch Rs 5,000 crore, which will take into account the main bridge, dykes on north and south banks, road network of 30 km, rail track of 74 km and six new railway stations among others.
