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

In addition to traffic flow guidance, at both ends of the Tra Khuc 2 bridge construction site, the contractor will install warning lights and encourage the dumping of sand on both sides of the bridge to create barriers to increase vigilance for vehicles traveling at night and prevent reckless overtaking when approaching the bridge. Simultaneously, at important intersections, relevant authorities will station personnel to regularly guide and direct traffic, prohibiting large vehicles from using routes outside the planned traffic flow.
