The police have urged motorists to avoid the Mrieħel bypass direction towards Marsa, which has been blocked by a fallen tree.
The tree fell at about 9.45am damaging a car parked opposite the Forestals showroom. No one was injured.
The road was fully reopened shortly after 11.30am.
It was the second such incident in as many days. A tree blocked part of Tal-Barrani road on Sunday.
In both cases, the trees collapsed as a result of strong winds.
