The first group of workers recently returned to work at the construction site of the Shanghai-Nantong Yangtze River Bridge in Zhangjiagang, East China's Jiangsu province.

Currently, more than 30 workers are busy installing wind barriers and placing box girders.

"In order to ensure the safety and health of workers, we are making the most of what limited resources we have to push forward construction," said a spokesman for the project.

The construction company has taken measures to prevent and control the spread of the novel coronavirus pneumonia.

Workers are required to wear masks at the construction site and when entering and leaving the living area. Offices, dormitories, and canteens are disinfected regularly.

Four quarantine areas have also been set up for workers before they start work.

The spokesman said all workers are expected to return to their posts by the end of February.

The bridge is the world's largest road-rail cable-stayed bridge, with a length of more than 11 kilometers and a main span of 1,092 meters.

It features a six-lane expressway on the upper deck and four railway tracks on the lower deck.

Construction on the bridge started on March 1, 2014 and is projected to be finished in March this year.
