Dover International Speedway (formerly Dover Downs International Speedway) is a race track in Dover, Delaware, United States. Since opening in 1969, it has held at least two NASCAR races each year. In addition to NASCAR, the track also hosted USAC  and the Indy Racing League. The track features one layout, a 1 mile (1.6 km) concrete oval, with 24° banking in the turns and 9° banking on the straights. The speedway is owned and operated by Dover Motorsports.
The track, nicknamed "The Monster Mile", was built in 1969 by Melvin Joseph of Melvin L. Joseph Construction Company, Inc., with an asphalt surface, but was replaced with concrete in 1995. Six years later in 2001, the track's capacity moved to 135,000 seats, making the track have the largest capacity of sports venue in the mid-Atlantic. In 2002, the name changed to Dover International Speedway from Dover Downs International Speedway after Dover Downs Gaming and Entertainment split, making Dover Motorsports. From 2007 to 2009, the speedway worked on an improvement project called "The Monster Makeover", which expanded facilities at the track and beautified the track. Depending on configuration the track's capacity is at 95,500 seats. It's grand total maximum capacity was at 135,000 spectators. 
In 1966, Melvin L. Joseph Construction Company, Inc.  began construction on Dover Downs International Speedway, which was specialized for horse racing and auto racing.  The race track was completed three years later,  and would have its first race on July 6, 1969.  The inaugural race, known as the Mason-Dixon 300, was won by Richard Petty. 
During the 1971 racing season, the speedway removed all the events not sanctioned by NASCAR to help keep focus on the two NASCAR Winston Cup Series races, which were 500 miles each.  Eleven years later, Dover Downs International Speedway added a NASCAR Budweiser Late Model Sportsman Series (now Xfinity Series) event, the Sportsman 200.  In 1986, the speedway added 3,200 seats to its 10,333 seat  grandstand.  Dover Downs International Speedway continued adding seats each year until 2001.   A second Xfinity Series race was also added to the speedway's schedule during the 1986 season. 
Eight years later, Delaware General Assembly passed legislation to allow slot machines at pari-mutuel horse racing venues.  In 1995, Dover Downs International Speedway replaced its asphalt surface with concrete, making it the second NASCAR Cup Series track after Bristol Motor Speedway to have a racing surface completely composed of concrete.  During the same year, Dover Downs slots opened on December 29.  Two years later, the speedway changed the race distances of its Monster Energy NASCAR Cup Series races to 400 miles, beginning with the 1997 fall race.  In 1998, Dover Downs International Speedway added an Indy Racing League event to the schedule,  but after two seasons the race was removed after the 1999 season.  During the 2000 racing season, Dover Downs International Speedway added a NASCAR Craftsman Truck Series (now NASCAR Gander Outdoors Truck Series) event.  Kurt Busch won the inaugural Truck Series race from the pole position. 
On September 23, 2001, the Cup Series returned to racing at Dover after the September 11 attacks for the MBNA Cal Ripken, Jr. 400, in which Dale Earnhardt, Jr. received the checkered and American flag at the same time.
In the following year, the speedway's capacity was expanded to 135,000 seats, the largest of any mid-Atlantic sport's stadium.  After the gaming side of Dover Downs separated, Dover Motorsports, Inc. was created to operate the speedway, which caused the speedway to become Dover International Speedway in 2002.  Two years later, the speedway announced the completion of the Monster Bridge, which is a glass-enclosed structure that has 56 seats over the third turn, and its fall NASCAR Cup Series race became the second race in the newly formed, NASCAR Chase for the Championship. 
On May 26, 2006, Dover International Speedway announced a multi-year capital improvement project called "The Monster Makeover", which would begin after the speedway's June NASCAR Cup Series race.  During the first stage of the improvement project in 2007, the speedway built a new 12-suite skybox complex and a new 2,100 square feet addition to the media center in the infield.  Other improvements included widened walkways behind three grandstands, renovated restrooms, more paved handicapped parking areas, expanded bus parking, as well as a sound system with improved audio quality for the grandstands. 
In 2008, the second stage of the "Monster Makeover" took place. During the stage, the Monster Monument, a 46-feet tall fiberglass structure, was built in the new Victory Plaza, the FanZone area was expanded, and an emergency services building was built.  One year later, the speedway continued the improvement project by replacing the front stretch pit wall to install a longer SAFER barrier wall that would make a wider and safer pit road, as well as an additional pit stall.   On December 30, 2011, Dover International Speedway announced that they will replace the 18 inch wide seats in the grandstands with 22 inch wide ones, reducing the capacity from 140,000 to 113,000 over the next two years. 
Shortly after the 2014 AAA 400, Dover International Speedway began removing 17,500 seats in turn 2 and the lower level of turn 3 as a result of declining attendance, reducing the track's capacity to 95,500. The removal of the seats was completed by Christmas 2014.   Also after the 2014 AAA 400, the track began work on a $2.9 million project to install a new catchfence that was ready for the 2015 season. The new catchfence is 21 feet (6.4 m) high, as opposed to the old catchfence, which was 15 feet (4.6 m) high.  The track's capacity was reduced to 85,000 in 2016 by removing seats in the upper level of turn 3.  In 2016, Dover International Speedway added 479 feet of SAFER barriers along the backstretch and turn three, and reduced the number of pit stalls available by increasing each stall by 2 feet (0.61 m). 
In 2019, Dover International Speedway built a new and expanded Cup Series garage, located between turns 1 and 2. The project also paved the inner portion of the track between turns 1 and 2 and replaced the guardrail in this area with a SAFER barrier. Work on this project, which cost $5.5 million, was planned to begin on May 6, 2019 and be completed by September 20, 2019, ahead of the race weekend in October 2019.  After the 2019 season, Dover International Speedway will remove 29,000 seats in the lower level between turns 3 and 4, reducing the track's capacity to 54,000. 
Since 2011, the track is the headquarters for the Monster Mash Marathon, a 42,195 metre and 21,097.5 metre running event that starts at the entrance to pit road, making one lap around the track, exiting at the start-finish line crossover gate, with runners making a run through Dover before finishing at the track entrance gate in front of the Miles the Monster statue. The race name references both its October date and the track's "Monster Mile" moniker. 
The speedway's mascot is called "Miles the Monster" which is a monster spawned from the track's nickname, "The Monster Mile."  The monster is featured on the winner's trophy, the track's tickets, memorabilia, website, and the 46-foot (14 m) Monster Monument.   A previous nickname that the track had was "White Lightning," used in the initial years after the track surface changed from asphalt to concrete.
