The 1970 event brought about the end of the 66 kilometer Mugello public road circuit; a seven-month-old baby was killed when local racer Spartaco Dini crashed his Alfa Romeo GTA into a group of people at the village of Firenzuola during a private test there, when the roads were open to the public (the roads were only closed on race day and for qualifying; and left open for every other day including open practice for the event).
O evento de 1970 significou o fin do circuíto de Mugello de estrada de 66 quilómetros, un bebé de sete meses de idade, morreu cando o piloto local de Spartaco Dini chocou co seu Alfa Romeo GTA contra un grupo de persoas no pobo de Firenzuola durante unha proba, as estradas estaban abertas ao público (os camiños soamente pechábanse o día da carreira e para a cualificación, e quedaban abertas o resto dos días incluíndo a práctica aberta para a carreira).
