Why does Tra Khuc 2 bridge through Quang Ngai have to be "closed" for 2 months?

In addition to traffic direction guidance, at the construction site at both ends of Tra Khuc 2 Bridge, the contractor will install traffic lights, encourage sand pouring on both sides of the bridge, and create obstacles to increase vigilance for vehicles traveling at night, and prevent reckless overtaking when moving to the bridge. At the same time, at important intersections, relevant agencies will arrange for people to be on duty regularly, guiding and directing traffic for heavy vehicles, and will not be allowed to enter routes outside the traffic planning.
