Walt Disney World Speedway, which were built during the 1990s construction boom but used for only four years. The historic Nazareth Speedway, which was paved in 1986, was completely abandoned after the 2004 season. Physically, the Milwaukee Mile, the oldest oval race track in the world, as well as the Rockingham Speedway and the Pikes Peak International Raceway still exist. However, these racetracks have not been used by nationally important motorsports events for years. There are only three 1-milers left on the NASCAR racing calendar: Phoenix, Loudon, and Dover. IndyCar has not raced on an oval of this length since 2018. Intermediate Also referred to with the general term of "speedway", these courses are 1 to 2 miles (1.6 to 3.2 km) in length, but the term is particularly reserved for 1.5-mile (2.4 km) tracks. At the beginning of the history of NASCAR and IndyCar, this oval size was not very common. Until 1990, there were only five examples. Two of these, the Marchbanks Speedway (1.4 miles) and the Trenton Speedway (1.5 miles), were demolished in the 1970s and 1980s, and only three—Charlotte Motor Speedway, Atlanta Motor Speedway and Darlington Raceway—have survived to this day. All other ovals of this type were built after 1994. During the race track construction boom of the late 1990s, these tracks began to be labeled with the rather derogatory term "cookie cutter" tracks, as their differences were perceived to be minimal. In 1992, Charlotte became the first intermediate track to install lights and allow for night racing. It is now commonplace for these types of tracks to host night races. Intermediate tracks usually have moderate to steep banking. Almost all modern race tracks that are still used in NASCAR and IndyCar today are of this type. Since their size allows them to compromise high speeds with sightlines, especially tri- and quad-ovals of 1.5-mile length have become commonplace in major racing series that use oval tracks. While intermediate speedways were designed primarily with stock cars in mind, they were also believed to be suited to host Indy cars as well. In the early years of the Indy Racing League, the series visited several intermediate tracks. The higher-downforce, normally aspirated IRL-type cars proved to be competitive at several of the tracks. The CART series however, mostly stayed away as the faster, more powerful Champ Cars were generally thought to be too fast for this type of
