San Marino Grand Prix
The area by Imola is home to several racing car manufacturers, including Ferrari, Lamborghini, and Maserati. Following the Second World War, the town started a project to improve the local economy. Four local motor racing fans suggested building a new road. The road would link together existing public roads. These road were used by the local car manufacturers to test their new car designs. Construction began in March 1950. The first test run took place two years later when Enzo Ferrari sent a car to the track.
