Kansas Speedway is a 1.5 miles (2.4 km) tri-oval race track in Kansas City, Kansas. The speedway was built in 2001 and currently hosts two annual NASCAR race weekends. The IndyCar Series also raced at the speedway until 2011. The speedway is owned and operated by International Speedway Corporation. International Speedway Corporation began exploring the idea of building a racing facility in the midwest in 1996. Attention was turned towards the Kansas City area in 1997. Officials considered both the Missouri and Kansas side of the city but eventually settled with the Kansas side because of better funding. Architecture firm HNTB, which also designed Chicagoland Speedway, was selected to design the facility, and firm Turner Construction was selected to provide construction management. Construction began on the 1,200 acres (490 ha), 1.5 miles (2.4 km) speedway in May 1999, and in July, preferred tickets went on sale.
