At around 2:40 p.m., locals passing through an eroded bypass section in Loc Son Ward saw a motorbike in a sinkhole, and an immobile man lying next to it.
Local authorities later confirmed the man to be 45-year-old Le Do Tuan Hoang.
The road section has been severely eroded since August, with authorities erecting warning signs and barricades on both ends.
However, a representative of Loc Son Commune People's Committee said some people have moved the barricades out of the way to ride their motorbikes through the area.
The bypass in Bao Loc City, which has so far cost VND800 billion (US$33 million), began construction in 2017. It was supposed to be completed after two years, but construction has stopped since 2019 due to procedure issues and a lack of funds.
The eroded section of the road spans 120 m, with numerous other sinkholes seen in the area.
Bao Loc City People's Committee has discussed the matter with relevant units, but the eroded section has yet to be fixed.
