From 4:30 a.m., the area at the foot of Vinh Tuy Bridge, in front of Aeon Mall Long Bien, was knee-deep in water. Vehicles crossing the bridge in both directions, toward the city center and toward Long Bien, backed up for kilometers. At times cars needed nearly an hour to get across. Many stalled, leaving their owners to push them roughly 400 m.
By 9 a.m. the water had dropped about 15 cm and more vehicles could get through.
From around 7 a.m., traffic began piling up on Dam Quang Trung Street and at the Co Linh-Dam Quang Trung intersection below Vinh Tuy Bridge, caused by the flooding and by construction at the intersection that had narrowed the roadway. By 9:30 a.m., although the water had receded to just under 10 cm, the jam still stretched the full length of Vinh Tuy Bridge, more than 3 km, mostly in the car lanes.
