Track Maps of the Past: Monzanapolis

There’s some fascinating things happening in this track map created for the 1958 “Race of Two Worlds” event at Monza. Unofficially dubbed “Monzanapolis” for the event, the race was a battle between American USAC speedway machines typically seen at Indianapolis versus European road racing machines. Because the race used only the banked oval portion of Monza’s fabulous double loop “combined” configuration (and it ran in the opposite direction), the event required it’s own map. They really outdid themselves with this one.
Not only does it show the track from above, there is also fantastic details like the cross sections of the banking, (this was where I learned that the North and South banking were so different) and an attempt to demonstrate the elevation change in the track (highly unconventional on a speedway).
I usually lean towards the freehand illustrated maps so commonly seen in CalClub and SCCA event programs, but this professionally drafted map is so rich in detail that I absolutely adore it.
