Hanoi recorded heavy congestion on many roads from 7 a.m. to 9:30 a.m. as tens of thousands of people traveled into the city center for work.
Cars move by inches on Thang Long Boulevard which is designed for speed of 80-100 km per hour.
The boulevard, spanning 140 meters, is one of the largest roads in Hanoi.
Traffic is also slowed on Hoang Quoc Viet Street in Cau Giay District, as fallen trees still occupy part of the road on Monday morning.
