One of the country's most popular music festivals starts in Chicago in a few days and that means traffic headaches for some motorists.
Sections of some roads in downtown Chicago are already being closed as Lollapalooza organizers set up for the three-day event that starts on Friday.
Around 100,000 people are expected to attend each day of the festival in Chicago's lakefront Grant Park. The rock band Kings of Leon and rapper Eminem are among this year's headliners.
Most streets shut down during the festival will reopen by early next. But a few sections will stayed closed for a few additional days as festival organizers clean up and haul away stages.
