The Ho Chi Minh City Department of Construction has just sent a document to the Ho Chi Minh City People's Committee proposing to approve the implementation of an emergency project to overcome landslides and subsidence of the Tau Hu canal embankment, and damage to the Ba Dinh road surface from regular funding - traffic maintenance.
The estimated implementation cost is about 100 billion VND, with completion time in August 2026.
The incident started on January 18, 2026, at the location opposite Hung Phu Park, near the Ba Dinh - Le Quang Kim intersection.
A part of the road surface, sidewalk and river embankment adjacent to the Tau Hu canal are subsided with a length of about 25 m, width of 16 m, and depth of more than 3 m. The surrounding area continues to show shifting and subsidence outside the initial collapsed pit.
February 2nd, the embankment eroded an additional 8 m towards the upstream of the Tau Hu canal, and collapsed on the road and sidewalks. The collapse scope extends about 12 m, the deepest position is nearly 1 m above the existing level. The high tide level on the same day caused some items to continue to erode.
From February 3rd to now, the area's ground has stabilized. Fortunately, the incident did not cause casualties or damage to vehicles, but damaged many parts of the embankment, road and sidewalk works.
The Ho Chi Minh City Department of Construction said that initial survey results show that sand and materials entering the sewer at the location of sewer D1. 800 at the foot of the embankment and sewer D500 under the collapsed pit are the direct cause of the incident.
However, the main causes of "sewer openings" need to be assessed in the context of a combination of many factors: complex geology - hydrology, flow, groundwater level, weak soil strata, subsidence during exploitation, impact of earthquake aftershocks, strata shift...
Therefore, the remediation work must follow an appropriate technical roadmap, with surveys using modern equipment to design thorough treatment solutions.
Due to the complexity, the Department has directed the Ho Chi Minh City Traffic Management and Technical Infrastructure Center to coordinate with consulting units to survey and propose appropriate remedial plans. The total estimated time is about 8 months, both surveying, designing, and constructing" - the document of the Ho Chi Minh City Department of Construction clearly stated.
