Following days of continuous heavy rainfall across Hong Kong, severe road damage has left drivers facing hazards ranging from deep potholes to sudden road depressions, according to local field reports and district inspections published on August 4, 2026. Drivers in multiple districts across Hong Kong Island, Kowloon, and the New Territories reported vehicle damage, including blown tires and jarring impacts, as municipal infrastructure struggles under the strain of prolonged wet weather.
Widespread Road Damage Across Hong Kong Districts
On-the-ground inspections revealed numerous road hazards spanning multiple neighborhoods. In Sheung Shui along Ma Sik Road near the Royal Ascot residential development, a sinkhole measuring over one meter in diameter formed, catching motorists off guard during evening hours and causing vehicle tires to sink directly into the cavity, with multiple drivers suffering blown tires as a result, according to local reports. On Hong Kong Island, a pothole measuring about one foot by one foot appeared on the center lane of Chai Wan Road near Fu Fai Gardens, while multiple smaller potholes with standing water emerged outside 11 Kat Hei Street in Chai Wan. In the New Territories, a drive from Fanling to Tai Po revealed at least five large potholes, including a depression exceeding one meter in diameter near the pumping station on Tai Po Road – Tai Wo Section, where private vehicles driving at high speeds became trapped, and deep pits near the intersection of Tai Wo Road and Ting Tai Road that caused heavy trucks to land hard with loud thuds. Industrial areas also sustained damage, with two large potholes filled with muddy yellow water reported at the intersection of Tai Fai Street and Tai Wang Street.
Kowloon Road Conditions and Pedestrian Hazards
Kowloon experienced severe road degradation, particularly around Mong Kok. At the intersection of Argyle Street and Fa Yuen Street, a previously patched pothole deteriorated once more, leaving a wide open gap that forced passing vehicles, including buses preparing for nearby stops, to swerve right or hug the edges of the road to minimize bouncing. Additional potholes marked the intersection of Argyle Street and Sai Yee Street, where even shallow depressions measuring only a few centimeters deep caused noticeable vehicle jolts. Some of these surface breaks formed directly across pedestrian crosswalks, creating tripping hazards for foot traffic.
Did You Know?
The Highways Department reported receiving approximately 10,000 complaints regarding damaged public roads between January and June of 2026, all of which were addressed within its established operational window.
Repair Methods and Official Response
Legislative Councillor Gary Chan Hak-khen noted that the worsening pothole conditions stem from persistent rainfall, explaining that patches applied by contractors often result in uneven surfaces or break apart within a week or two due to differences between old and new materials. Chan suggested that crews should cut wider and deeper foundations for severe potholes before paving. However, Chan pointed out that such repairs often face procedural bottlenecks, as work on expressways requires nighttime road closures, while urban repairs demand environmental permits. Because complete road closures are difficult to implement, contractors frequently rely on rapid material filling. Chan urged the Highways Department and the Environmental Protection Department to improve coordination so crews can complete comprehensive repairs when necessary rather than relying on endless patching.
Expert Insight:
Balancing rapid public safety interventions with durable infrastructure repairs remains a central operational challenge for municipal authorities during prolonged severe weather cycles, as procedural hurdles often limit the scope of immediate maintenance work.
In response to inquiries, the Highways Department stated that it regularly inspects public roads under its purview and dispatches inspection teams promptly upon receiving damage reports. The agency maintains a target of completing repair work within 48 hours of notification, a benchmark it reports meeting across all pothole repair cases over the past three years. Between January and June 2026, the department addressed approximately 10,000 complaints regarding road surface damage. Since April 2025, the department has adopted high-modification asphalt for paving to enhance durability and reduce repair frequency while maintaining rapid drainage. Furthermore, the department is introducing new repair materials capable of setting directly in wet environments to shorten post-rain repair times.
