Chicagoland Speedway is an inactive 1.5 mi (2.4 km) tri-oval intermediate speedway in Joliet, Illinois. It has hosted various major races throughout its existence, including NASCAR and IndyCar races. The track is currently owned by NASCAR, and features a 47,000-seat capacity as of 2019.

During the 1990s stock car racing boom, NASCAR, the Indianapolis Motor Speedway, and Menards formed the Motorsports Alliance to find a new market to construct an intermediate oval, eventually deciding on the Chicago market. After failed proposals at the DuPage Airport and the town of Plano, the city of Joliet was chosen after the Alliance partnered with the Route 66 Raceway in 1999. Construction began within the year and was completed in 2001. After 18 years of racing, due to attendance woes, all major racing at the facility stopped. Since 2020, with the exception of a one-off SuperMotocross race in 2023, the facility has stayed largely dormant.

Chicagoland Speedway in its current form is measured at 1.5 miles (2.4 km), with 18° of banking in the track's turns, 11° of banking on the frontstretch, and 5° of banking on the backstretch.^[1] Unlike most intermediate oval tracks, the backstretch is a singular continuous curve instead of a straight line.^[2] The track's length has been disputed by varying sanctioning bodies; NASCAR utilized a length of 1.5 miles (2.4 km)^[1] while the IndyCar Series utilized a length of 1.52 miles (2.45 km).^[3]

Chicagoland Speedway is located in Joliet, Illinois, and is served by Illinois Route 53 and Interstate 80.^[4] As of 2019, the facility has a seating capacity of 47,000 according to Forbes.^[5] The entire facility encompasses approximately 930 acres (380 ha) of land according to the Journal Star.^[2]

In December 1996, DuPage Airport officials began hearing proposals of the construction of a potential racing facility on land owned by the airport.^[6] Out of three proposals, the one chosen by the airport's board was a 1.5-mile (2.4 km) intermediate oval funded by the Motorsports Alliance, a partnership between International Speedway Corporation (ISC), the Indianapolis Motor Speedway, and Menards.^[7] Initial plans for the $50 million proposal included seating capacity for 40–80 thousand and an opening date in 1999.^[8] The proposed racetrack quickly faced opposition; by February 1997, numerous anti-racetrack groups were formed, including in West Chicago and Geneva.^[9] Two months later, the plan was killed after numerous factors, including increasing public opposition, concerns about the track's environmental impact, and disagreements between DuPage Airport officials and the Motorsports Alliance in lease revenues made the location unfeasible.^[10] In August 1997, the Motorsports Alliance announced plans to pursue a location in either Plano, Illinois, or northwest Indiana.^[11] By February 1998, the proposal was narrowed to Plano;^[12] however, by January 1999, the plan was scrapped in favor for a proposal in Joliet, Illinois.^[13][14]

On January 6, 1999, The Charlotte Observer reported that the Motorsports Alliance was seeking to annex 930 acres (380 ha) in Joliet, with a hearing scheduled on the 19th for its approval.^[13] The location was later revealed to be a plot of land northeast of the Route 66 Raceway, with the owners of Route 66 Raceway partnering with the Alliance's proposal.^[15] On the 19th, the Joliet City Council unanimously approved the $100 million, 75,000-seat project.^[16] Within the month, the Motorsports Alliance spurred efforts for the plot of land to be included into the Des Plaines River Valley Enterprise Zone for a tax break worth up to $10 million over 10 years,^[17] which was fully approved four months later.^[18] In response to local residents' concerns regarding traffic, in February, the Alliance promised to invest $3.7 million towards nearby road improvements.^[19] In May, the Alliance announced plans to start construction in the summer of 1999 and open sometime in 2001.^[20] That same month, the Alliance and Route 66 Raceway owner Dale Coyne formed a joint company named Raceway Associates to run the facility, with the Alliance owning 75% and Coyne owning 25%.^[21] Two months later, NASCAR executive Mike Helton confirmed discussions about adding a potential NASCAR Winston Cup Series to their schedule for the 2001 season.^[22] By August, earthmovers began preparing the land for groundbreaking.^[23]

Groundbreaking on the facility occurred on September 28, 1999, with NASCAR driver Dale Earnhardt appearing as a dignitary.^[24] On May 8, 2000, track officials officially confirmed the addition of the facility to both the NASCAR Winston Cup Series and the Indy Racing League (IRL) for 2001; additionally, the track was also formally named as the "Chicagoland Speedway",^[25] with Joie Chitwood III being named as the general manager of the track.^[26] By September 2000, construction on the facility was "more than half done" according to Southtown Star writer John Debberstein,^[27] with the track itself being described as a 1.5-mile (2.4 km) oval with 18.5° of banking in the track's turns, 11° of banking on the frontstretch, and 5° of banking on the backstretch.^[28] The first tests done on the facility were conducted on October 26, with drivers John Andretti and Scott Sharp driving a NASCAR Cup car and Indy-car, respectively.^[29] On February 1, 2001, the only construction fatality occurred when worker Ehren Brandau fell while installing windows to a skybox.^[30][31] By the end of the its construction, the entire facility cost approximately $130 million (adjusted for inflation, $223,694,794).^[32][33]

Chicagoland Speedway officially opened to the public on July 12, 2001, for practice sessions for the 2001 Tropicana 400, a Cup Series race.^[34] The track's first race, a second-tier NASCAR Busch Series (now called the Xfinity Series) race, was ran two days later with Jimmie Johnson winning the first race at the track.^[35] A day later, the Tropicana 400 was ran, with Kevin Harvick winning the first highlight race at the facility.^[36] The track's first Indy Racing League (now called the IndyCar Series) occurred on September 2, with Buddy Lazier winning the event.^[37] A year later, the track recorded the closest finish in IndyCar history, with Sam Hornish Jr. winner over Al Unser Jr. by 0.0024 seconds.^[38] In 2003, Matthew Alexander replaced Chitwood as the general manager of Chicagoland Speedway.^{[‡ 1]} The following year, SAFER barriers were installed throughout the entire outside perimeter of the track at a cost of approximately $1.5 million.^[39][40]

In February 2007, ISC bought out Raceway Associates for $102.4 million, taking full control over both Chicagoland Speedway and Route 66 Raceway.^{[‡ 2]} A month later, Alexander was promoted to president of the speedway.^{[‡ 1]} Within the year, Alexander announced the installation of lights to accommodate night racing;^[41] the $17 million installation was completed in time for the 2008 LifeLock.com 400.^[42] In 2009, Alexander stepped down as president of the speedway, with Craig Rust replacing Alexander.^[43] Rust's tenure was brief; he stepped down in September 2010^[44] and was replaced by Scott Paddock four months later.^[45] In the 2010s, the track underwent two seating capacity declines due to attendance declines: one in 2013 that decreased capacity to 55,000,^[46] and one in 2019 that decreased capacity to 47,000.^[47] Also in 2019, the facility was bought out by NASCAR when the sanctioning body bought out ISC.^[48]

Although a NASCAR Cup Series race was scheduled in 2020, the race was cancelled due to the COVID-19 pandemic.^[49] In May 2020, plans were made to convert 82 acres (33 ha) of the facility's parking lots into warehouse storage;^[50] however, the plan faced opposition from the Joliet City Council Economic Development Committee^[51] and was rejected by the Joliet Plan Commission in August.^[52] In September, NASCAR announced that all three national series would not return to Chicagoland Speedway for the 2021 season, leaving the track with an uncertain future.^[53] Paddock resigned as president a month later.^[54] The track was left widely dormant in the following years after NASCAR's departure. In 2022, the track was used to store vehicles awaiting computer chips from the Ford Motor Company in the midst of the 2021 global semiconductor shortage.^[55] The following year, the SuperMotocross World Championship announced that they would host races at the facility for their 2023 season;^[56] the races ran in September, becoming the first motorsports event at the facility in over four years.^[57][58]

From 2001 to 2019, Chicagoland Speedway hosted annual one NASCAR weekend: the Camping World 400.^[59] In 2011, the race moved from a July slot into September, becoming the first race of the NASCAR playoffs.^[60] Seven years later, the race was moved back to its July date until it was dropped from the schedule starting in 2020.^[61][53] Along with its Cup Series races, the facility also ran second-tier Xfinity Series and third-tier Truck Series with the Chicagoland 300 and the Camping World 225 as support events for the Cup Series.^[59] From 2011 to 2015, the speedway also ran a second standalone Xfinity Series weekend with the Owens Corning AttiCat 300.^[62][63]

From 2001 to 2010, Chicagoland Speedway hosted one annual IndyCar Series weekend: the Peak Antifreeze Indy 300. In 2006, the race was moved to become the season finale of the IndyCar season.^[64] The move lasted for three seasons; in 2009, the season finale was switched for the Homestead–Miami Speedway.^[65] The race was dropped after the 2010 season.^[66]
