The Cross-Harbour Tunnel was forced to shut partially for more than an hour on Tuesday after a piece of concrete fell from the ceiling and hit a vehicle.

Police said they received a report shortly after 1pm of a car travelling through the tunnel being hit by a concrete slab that measured about 50cm by 50cm.

No one was hurt in the incident.

The Hong Kong Island-bound fast lane was closed for emergency repair works, leading to congestion. It was reopened to traffic at 2.48pm.
