In the wake of the 1955 Le Mans disaster , the championship was still open after the British Grand Prix ; although after that race (with the French Grand Prix already having been cancelled) the German, Swiss and Spanish Grands Prix were all cancelled. This meant that Fangio won the world driver's championship for the 3rd time and the 2nd time in succession.
The Monza circuit near Milan had been revamped and resurfaced, and had been given all new pit and safety facilities. A new concrete banking had been constructed over where the original slightly banked version was, and the combined 10 km (6.214 mi) Monza circuit was used for the first time since 1933. The Curva Sud had also been modified from 2 right hand corners into one sweeping right-hander known as the "Parabolica", where run-off area was implemented.
