DHAKA, Jan. 14 (Xinhua) -- Chinese engineers on Tuesday installed another span of Bangladesh's largest Padma Bridge, making over 3 km of the bridge visible so far.
With the installation of the 150-meter long span, the 21st span among the 41 spans has been installed on the 6.15-km bridge and 3,150 meters of the bridge is now visible.
The bridge constructed by the China Major Bridge Engineering Company is expected to be opened by 2022.
The bridge has two decks -- upper deck road transport and lower deck for railway tracks.
In December 2015, Bangladeshi Prime Minister Sheikh Hasina inaugurated the main works of Padma Bridge project, the biggest of its kind for the country.
Apart from connecting nearly 30 million people in Bangladesh's southwest region to the rest of the country, the bridge will enhance regional trade and collaboration along the Asian highway No. 1 and the Trans-Asian railway network.
