Chicago Street Circuit

Circuit History

NASCAR has been on something of a mission in recent years to spice up the show and bring its form of entertainment to new fans. An expansion of road course racing has followed, along with more innovative changes, such as the Bristol Dirt Race and the Busch Clash at LA Memorial Coliseum. Street racing, therefore, was perhaps the next logical extension.

Discussions had been taking place with the Chicago authorities for a number of years, with the area around Green Park identified as a home for a street race. That decision brought echoes of a decades earlier attempt to organise a Chicago street race; in September 1980, a Chicago Grand Prix was announced as part of the following year’s CART Indycar championship, with the event to take place on Independence Day, with a Can-Am race the following day.

The then Mayor Jane Byrne called it “an excellent way to showcase our city to the rest of the world.” Sadly, opposition soon mounted to the course, which was set to measure 2.7 miles and feature 11 turns. Opponents branded it a distraction from more important problems facing Chicago, such a crime and poverty. Disruption to major traffic routes were also cited and after just 44 days the event had been canned.

Fast forward 40 years and that opposition had faded, to the point that city authorities were once again ready to embrace the idea of racing. With NASCAR keen to establish a new home in Chicago, closer to the downtown area than its own Chicagoland Speedway, the idea was once again revived.

A virtual start becomes a reality

Perhaps unusually, NASCAR took the decision to employ iRacing to identify the layout of the circuit, using their expertise to create a virtual circuit, albeit with the intention of also creating the real thing in due course.

During the autumn of 2020, iRacing staff headed to downtown Chicago to scan the city streets with the goal of devising a viable racetrack. From these efforts, a recommendation of which streets would prove most suitable was put forward and a green light was given to produce the circuit in virtual form. Data from iRacing online sessions featuring the track and numerous races with drivers from the eNASCAR Coca-Cola iRacing Series, the premier NASCAR esports series on iRacing, helped to hone the project.

The layout was then approved and unveiled for an eNASCAR iRacing Pro Invitational Series event that was televised live in June 2021. Fast forward to the next month and the announcement that the virtual circuit was going to become a reality in 2023, marking the first time the premier series had been seen on a street course.

“Seeing NASCAR on the streets of Chicago become a reality is a major accomplishment, and iRacing is thrilled to have played a part,” said iRacing executive vice president Steve Myers. “In recent years, the leading brands in motorsports have relied on iRacing to not only simulate their existing products, but also to experiment with new car and track concepts. Taking the NASCAR Cup Series to the streets for the first time in Chicago is a direct result of our work together, and we’re looking forward to seeing the concept come to life!”

The 2.14-mile, 12-turn circuit that was released to all iRacing members features many of the city’s iconic landmarks in the backdrop, including Grant Park and the Buckingham Fountain.

NASCAR arrives to wet weekend

The debut event weekend was set for early July 2023, with the Chicago race replacing Road America on the Cup Series schedule. A NASCAR Xfinity race was also included on the schedule, with concerts from The Black Crowes, The Chainsmokers and Miranda Lambert on Lakefront Green adding to the entertainments.

Saturday's Xfinity race thus had the honour of being the first NASCAR-sanctioned street race, though the weather gods intervened to ensure that it was a much shortened affair. Cole Custer led all 25 laps before lightning strikes in the area caused NASCAR to red flag the race and then to postpone completion until Sunday morning. But the rain persisted, leaving officials with little choice but to declare the race three laps short of halfway and five laps short of the completion of Stage 2. Stewart-Haas Ford driver Custer was thus the track's first winner.

Explaining the decision, NASCAR said: “With standing water and flooding a significant issue at the race track and throughout the city, there was no option to return to racing prior to shifting to NASCAR Cup Series race operations. Throughout the entire planning process for the Chicago Street Race, our relationship with the City of Chicago has been strong and among the most valuable assets in reaching this historic weekend.

“In the spirit of that partnership, returning on Monday for the completion of a NASCAR Xfinity Series event two laps short of halfway was an option we chose not to employ. Based on several unprecedented circumstances, NASCAR has made the decision to declare Cole Custer the winner of the race.”

Rookie sweeps all before him

The Sunday rain caused the Cup Series race to start an hour behind schedule, with the track still very wet though eventually drying out. NASCAR’s decision near the midpoint of the event to shorten the race from the scheduled 100 laps to 75, put a large group of cars that had pitted on Lap 43 inside their fuel window. Among them was Kiwi driver and Australian Supercars champion Shane van Gisbergen, competing in his first NASCAR race as part of Trackhouse Racing’s Project 91 program. He moved his way up through the field from 18th all the way to the lead. Despite a late caution causing an overtime finish, the rookie driver held on take the first Cup Series win on the streets. It was the first debut race win since Johnny Rutherford in 1963.

Despite the weather, both fans and drivers were largely positive. Xfinity driver Justin Allgaier praised the unique setting, while Cup racer Chase Briscoe commented that it had “raced better than I thought it would” and hoped for refinements in future editions.

The 2024 and 2025 editions continued with solid support and improved operations (and a second win for van Gisbergen in the latter), but lingering logistical challenges—combined with a push to rebalance the Cup Series schedule—eventually led NASCAR to pause the event.

A pause for 2026

On 18 July 2025, NASCAR announced that the Chicago Street Race would be put on hold for the 2026 season, with a possible return in 2027 under review. The decision followed continued discussions with city officials and the need to find a more favourable calendar slot, after weather disruptions and operational complexity proved persistent concerns.

A statement shared to the event’s social media accounts read: “Following the success of the first three years, the Chicago Street Race will hit pause in 2026 to afford us the time necessary to work collaboratively with the City of Chicago to explore a new potential date and to develop a plan that further optimizes operational efficiencies, with a goal to return to the streets of Chicago in 2027.

“Together, we have built and grown an expanded community of fans that consists of longtime NASCAR enthusiasts and first-time racegoers from around the globe, and for that, we are immensely grateful.”

While the event was widely recognised as a bold and innovative step, its future now depends on further negotiations between NASCAR and the City of Chicago. For now, the streets will fall silent—but the story may not be over just yet.
