According to the Road Management Office III.1, due to the impact of storm Tra Mi, many sections of Ho Chi Minh Road in Da Nang suffered from landslides on the slope of the positive slope, with rocks and soil filling the longitudinal ditches, with a volume of about 2,000m3. The rock retaining wall on this section of the road was also pushed, rocks and soil filling the longitudinal ditches and roadside. Many culverts and longitudinal ditches on the route and about 250 trees with a diameter of 10 - 20cm fell on the protective fence and many signs were knocked down.
The stream flow caused erosion, eating deep into the base of the T9 pier, causing some sections of bored piles to be exposed. Upstream and downstream, the culvert bed, the collection pit, and the culvert yard were partially filled with soil. Many sections of the culvert had their slopes eroded, the head walls, wing walls, and culvert yard were damaged, a downstream culvert section was eroded, and many trees fell onto the road.
On October 29, Road Management Office III.1 said that immediately after the damage to traffic works caused by storm Tra Mi, the unit directed management and maintenance contractors to regularly deploy human resources, machinery and equipment to clear soil, rocks, and fallen trees to ensure traffic.
