The Chicago Street Course is a street circuit located in the city of Chicago, Illinois, United States. It hosts the NASCAR Cup Series and NASCAR Xfinity Series. The track was initially a conceptual track on iRacing made for the eNASCAR iRacing Pro Invitational Series in 2021.
The track for the race ended up being the exact same layout as the version used in 2021 for the eNASCAR iRacing Pro Invitational Series. The start/finish line is located on South Columbus Drive in front of Buckingham Fountain in Grant Park. The cars will go south and then turn left onto East Balbo Drive and then right onto South Lake Shore Drive (also part of U.S. Route 41), which is alongside Lake Michigan. The cars will then turn right onto East Roosevelt Road and then make another right, which gets them back onto South Columbus Drive where they are going north. They will then reach the intersection of South Columbus Drive and East Balbo Drive again and will make a left turn. When they are back on East Balbo Drive, they will cross a bridge over the Metra Electric District tracks. Next, the cars will turn right onto South Michigan Avenue and go north, onto East Congress Plaza Drive, and back onto South Michigan Ave. Lastly, they will make a right turn onto East Jackson Drive, go back across the Metra Electric tracks, and right back onto South Columbus Drive to the start/finish line.
