Lollapalooza wraps up first night in Chicago

CHICAGO (WLS) -- Despite some Friday afternoon rain, music lovers packed into Grant Park for the start of Lollapalooza, the annual three-day music festival featuring five stages and more than 100 artists.

Tickets have been sold out since April and the 300,000 people are expected to bring in an estimated $120 million of economic impact into the city, as about 80 percent of the concertgoers are from out of town.

The first day of the three-day festival saw performances from musicians including Lucius, Iggy Azalea, Lykkie Li, Interpol, Arctic Monkey and Lorde. Friday night's headliner is Eminem.

Saturday and Sunday will feature sets from a variety of artists including Jenny Lewis, Grouplove, Spoon, Nas, Foster the People, Calvin Harris, Chance the Rapper, Cage the Elephant, Childish Gambino, Skrillex and many more. Saturday's headliner is Outkast, and Sunday's headliner is Kings of Leon. Three-day and one-day passes are sold out.

Lollapalooza is held in Grant Park, and residents and visitors should expect to encounter increased traffic over the weekend due to attendees, as well as the detours and road closures in and around the park. Streets closed for the festival are:

- Columbus Drive between Roosevelt and Monroe

- Jackson Drive between Michigan and Lake Shore Drive

- Congress Parkway between Columbus and Michigan

- Balbo Drive between Michigan and Lake Shore Drive

- Congress Plaza

Nine bus routes in the Loop have been detoured due to these street closures. CTA is also increasing and extending train service on the Blue, Brown, Green, Orange and Red lines beginning today and lasting through Sunday.

Additional traffic downtown is expected as this weekend also hosts Bears Family Fest. Residents and visitors are encouraged to use public transportation to decrease downtown congestion, and the CTA is recommending that all customers plan for extra travel time.
