The waters converged on a section of the highway near Di An City in Binh Duong and Bien Hoa City in Dong Nai. Both are major industrial hubs bordering Ho Chi Minh City.
In the worst flooded parts, there was nearly a meter of water, which caused many motorbikes to stall.
“The water flow was really strong and many people fell with their motorbikes,” Hung, a resident of Tan Dong Hiep Ward in Di An, said.
The water flows rapidly at the intersection of Highway 1K and the road leading to Chau Thoi Pagoda in Tan Dong Hiep Ward.
Many locals helped motorcyclists who took tumbles.
"Within just 30 minutes a few dozen people fell," Lam, a quarry worker who helped falling up riders, said.
There was white foam in most places as companies in the upstream area took advantage of the heavy rain to discharge wastewater.
"We see this often," Hang, a resident of Tan Dong Hiep Ward, said.
“When there is foam in the water everyone’s feet get itchy by evening.”
The Chau Thoi gas station on highway 1K was under nearly a meter of water and vehicles could not fill gas there.
There are often accidents when the section of Highway 1K in Hoa An Ward is flooded, and so authorities have to set up warning signs.
Many people sat on their motorbikes and waited for the water to recede to go home.
"I've been waiting for more than 30 minutes hoping the water will recede quickly so I can pick up my child from the kindergarten," Lan, who works at Changshin Vietnam Company in Bien Hoa City, said.
