Motorists this afternoon were advised to avoid the area near the tunnels under the Msida Skate Park.
The police explained that both lanes going North and one lane going the opposite side were closed after a car crashed into a lamp post, causing the pole to fall across the road.
A man was slightly injured.
The incident happened at 5pm. Some of the lanes were reopened about about two hours but traffic to St Julian's was still being diverted at 7.45pm
