Part of Regional Road was temporarily closed to traffic following a car crash that caused long tailbacks of traffic.
The crash happened at around 7am, the police told Times of Malta.
Two cars were involved - a Mazda Demio and a Kia Picanto - with one of the drivers being rushed to Mater Dei Hospital.
The man, a 22-year-old from Marsa, was later certified to have suffered slight injuries.
A 19-year-old woman from Tarxien who was behind the wheel of the Mazda, was uninjured.
Part of the road - in the direction towards Santa Venera - was closed to traffic temporarily but motorists complained of tailback leading all the way to the Tal-Barrani area in Żejtun.
Just last week, debris from a major crash on the same road took hours to be removed, causing long traffic tailbacks on the key thoroughfare.
