With people returning to HCM City from the Cuu Long (Mekong) Delta after Tet (Lunar New Year), highways have been severely congested in the past two days.
Most offices reopen on Monday (February 11), and workers are flocking back, causing traffic jams on National Highway 1A and Highways 60 and 50.
National highways section in Tien Giang Province has experienced relentless congestion since Friday, with traffic mostly crawling on National Highway 60 from Ben Tre Province.
National Highway 1A sections in Vinh Long Province have been similarly congested since early Saturday morning.
Traffic through the Rach Mieu Bridge has been stop-go since Saturday though the toll booth at the bridge has shut down many times to ease things.
The narrowness of the bridge means traffic is backing up for five kilometres up to Ba Lai Bridge.
The provinces have assigned officers to regulate traffic on highways and bridges.
Many travellers are resting and taking photos on the Can Tho and My Thuan bridges, exacerbating the traffic chaos.
Tens of thousands of vehicles from the delta will continue travel to HCM City in the next few days and more traffic jams are expected at many intersections and sections of National Highways 1A and No 50, the HCM City-Trung Luong Expressway, the Rach Mieu and My Thuan bridges, and many other small bridges.
