Prime Minister Sheikh Hasina today laid the foundation stone of a 4.8km double-line dual-gauge Bangabandhu Sheikh Mujib Railway Bridge -- aimed at boosting rail communication between the capital and western zones of the railway.

Once constructed, the dedicated dual-gauge double-track railway bridge over the Jamuna River, which will be built some 300 metres upstream of the Bangabandhu Bridge that has a single rail line, would be the largest dedicated rail bridge in the country.

The Prime Minister laid the foundation stone virtually from her official residence Gono Bhaban.

Bangladesh Railway, along with the consultant organisations -- Oriental Consultants Global Company Limited and Chodai Company Limited of Japan and Development Design Consultants Limited of Bangladesh in association with ACE Consultants Limited of Bangladesh -- have already completed a detailed design of the railway bridge.

The main bridge will be constructed in two phases. Two separate agreements have already been signed with Obayashi-TOA-JFE, Japan and IHI-SMCC JV, Japan for eastern and western parts of civil works respectively.

A joint venture of Obayashi Corporation, TOA Corporation and JFE would construct the eastern part of the bridge at a cost of Tk 6,801 crore, while another joint venture of the IHI and SMCC will work on the western part which will cost Tk 6,148 crore.

As per the agreements, land was handed over to both contractors in July this year.

The main project operations include the construction of a 4.8km long dual-gauge double-track bridge, construction of a 7.6km long double-line railway approach embankment, erection of 30.73km dual-gauge railway track, construction of 16 railway approach viaducts, minor bridges and culverts, renovation and remodeling of Bangabandhu Bridge East and Bangabandhu Bridge West stations and yards.

The new bridge will be able to run trains at a speed of 120 kmph on broad gauge line and 100 kmph on metre gauge track. With the construction of the Bangabandhu Sheikh Mujib Railway Bridge, 88 trains will be able to run.

The project is scheduled to be completed by 2025.
