A high vehicle hit the bridge over Triq Ħal Qormi this evening but the structure's stability and safety does not appear to have been compromised, Transport Malta said.
The police said no one was injured. The vehicle was being driven towards Qormi.
TM carried out an immediate preliminary inspection but it will be carrying further tests over the coming days to establish what works need to be carried out to repair the damage.
TM is also liaising with the police to get the details of the vehicle involved.
