Two different accidents involving trailer lorries closed the A-7 motorway twice last Sunday.
Fire inspectors believe the lorry caught fire after a wheel exploded.
The driver and passenger were able to escape from the blaze unhurt and alerted the authorities.
Although the blaze was quickly put out, when a tow truck tried to move the remains at 10:30 the next morning the fire started afresh, and fire units had to return. The motorway was closed in the north bound direction until 13:30 Sunday afternoon.
And in a separate incident Sunday morning, an articulated trailer also carrying fruit overturned on the motorway near Húercal de Amería, at km point 449 on the south bound carriageway.
The motorway was blocked for several hours whilst the lorry was removed and the fruit cleared up.
