As firefighters from the provinces of Gorizia, Udine and Trieste joined forces to battle the blaze, traffic on the A4 motorway had to be diverted, and the local rail line services suspended.
As a precautionary measure, several families were evacuated from their homes due to the fire in the Guncina area, near Bolzano.
The fires are the latest in a string of emergencies that have threatened various communities across Italy, as the country undergoes one of the hottest heatwaves on record.
The extreme drought conditions have led to rivers and reservoirs drying up, making it increasingly difficult for firefighters to battle the infernos, emergency services have stated.
Temperatures are expected to rise to 42 degrees Celsius in many Italian cities next week, which authorities predict will fuel wildfires across the country.
