A trailer carrying a container just missed hitting the footbridge at Aldo Moro Road in Marsa this morning.
The incident happened at about 11.15 a.m.
The driver apparently thought he had had enough clearance but realised at the last moment that he didn't and promptly stopped the trailer.
There was some traffic confusion until the trailer was reversed.
An excavator being carried on a trailer crashed into the bridge last April 23, causing traffic chaos for several hours.
