The truck, which was carrying boxes of clothes that were scattered on the road, skidded off the road without causing any injuries, with the alert being given at 05:35 am, a source from the Algarve Sub-Regional Command told Lusa.
Via do Infante reopened to traffic at 2:34 pm, the time needed, according to Civil Protection, to remove and clean the affected section.
The accident took place between the Loulé-centro and Loulé-sul junctions in the west-east direction of the motorway that connects Lagos and the border with Spain at Castro Marim/Vila Real de Santo António, in the district of Faro.
A total of 16 firefighters, GNR and personnel providing assistance on Via do Infante were involved in the incident, supported by eight vehicles, according to the same source.
