Vietnam's first expressway has developed sinkages just two months after it opened to traffic, officials say.
Nguyen Van Cong, a spokesperson for the Ministry of Transport, said Tuesday the 39.8 kilometer long Ho Chi Minh City Trung Luong Expressway has sunk at four spots.
However, he added that the sinkage was still within permitted levels according to regulations on roads built on weak soil.
The road was opened to traffic on February 3, when only four-wheeled vehicles were allowed.
Cong said the expressway was being used temporarily to reduce traffic jams and accidents between HCMC and the Mekong Delta. It has not been officially completed yet.
The road helps cut travel time between the two localities by an hour compared to using National Highway 1A.
My Thuan Project Management Unit has asked contractors to fix the sinkage problem.
Many minor tasks such as erection of signboards and fences, and the drawing of lines between lanes have not been completed on the road.
