Crews clean up Grant Park after Lollapalooza wraps up

CHICAGO (WLS) -- The fun at Lollapalooza has come to an end. The four-day music festival wrapped up Sunday night.

Overnight, workers began cleaning up the incredible amount of trash dispersed all over Grant Park. Crews also started deconstructing tents and stages.

Streets will stay closed around Grant Park until at least Tuesday as the clean-up continues.

Organizers said 40,000 people attended this year. It was expanded this year to four days to mark its 25th anniversary and will also be four days next year.
