More than 1.5 million pounds of dirt will cross through San Diego Tuesday and Wednesday.
The dirt will be headed for San Diego’s Petco Park, where officials are preparing the Monster Energy Supercross Race Track. The inaugural race will take place Saturday night.
Five hundred truckloads of dirt will become a man-made dirt battleground for the Supercross race.
It will be the 32nd time the race has visited San Diego and the sixth race of the 2015 season, but it will be the first time the race visits Petco Park.
