The two tunnels, some 800 meters long, will be part of Vietnam’s first railway with an underground section.

Japanese general contractors Shimizu Corp. and Maeda Corp.  will build the tunnels using the so-called shield method, which allows them to dig the tunnels with excavators while curbing ground vibrations and noise. It will take one year to complete the work.

The railway, scheduled to go into operation in November 2020, will serve as a new means of transportation for commuters while being expected to help ease chronic traffic congestion in Ho Chi Minh City. (Jiji Press)
