A section of the road between the Regional Road and the Coast Road is to be widened to eliminate a traffic bottleneck.
The project, in Triq San Andrija, is due to get under way in the winter and will see the road widened uniformly, to have two lanes in either direction.
Parts of it are currently narrow, mostly because of junctions, which will be redesigned.
The works will be handled by Infrastructure Malta, the new government agency responsible for road works.
