Hundreds of thousands of fans packed the streets for the Dodgers' championship parade to celebrate their World Series win over the Yankees ... an event so big, it cost Los Angeles over $2 million to have emergency personnel on hand to make sure folks were safe.
But, don't fret ... the team's going to make the city whole.
TMZ Sports has learned the World Series parade cost the Los Angeles Police Department $1,738,621.19 ... almost entirely for a gang of extra officers to man the event.
