Contractors work overnight to reopen collapsed Hai Ran road by Monday

More than a dozen contractors worked through Sunday to complete emergency repair work on the Sham Shui Po subsidence site, aiming to reopen the area by early Monday.

The road collapse at the junction of Hai Tan Street and Kweilin Street in Sham Shui Po measured around 8 by 12 meters and 4 meters deep. Police received a report on Friday about the sinkhole and immediately cordoned off the area. 

A bucket truck removed debris from the subsidence, including manhole covers and large bricks. Live footage showed exposed wires, water pipes and constant seepage from the cave. A dump truck delivered sand and gravel into the hole, later compacted by a road roller. 

Authorities aim to reopen affected roads in phases starting Monday morning while investigating the cause of the collapse. The fast lane of the affected road is expected to reopen by 6 am tomorrow, while the slow lane is set to reopen on Wednesday (Jun 5).

Following inspections on Saturday night, the Water Supplies Department found no damaged water pipes.

However, the Drainage Services Department confirmed two roughly 2-meter deep sewers of 225 mm diameter and a 300 mm storm drain were partially damaged.
