Motorists have been urged to avoid the roundabout near the Mosta Technopark area due to major road works taking place there until tomorrow evening.
Transport Malta said alternative routes through Birkirkara, Naxxar or San Ġwann could be used.
It said it was “actively addressing” the impact these major works were having on road users by assigning enforcement officers to assist in traffic direction. But it also called on “the cooperation of the public to avoid the area unless absolutely necessary”.
