Music City Motorplex is a NASCAR Dodge Weekly Series racetrack located at the Tennessee State Fairgrounds near downtown Nashville, Tennessee. The track is one of the oldest tracks in the United States. The track held NASCAR Grand National/Winston Cup (now NEXTEL Cup) races from 1958 to 1984, when it was called Nashville Speedway USA. The winner's trophy for NASCAR races held at the track was a Les Paul guitar from Gibson.

Track Configuration History
Nashville Speedway USA is currently an 18 degree banked paved oval. The track is 0.596 mile long. Inside the larger oval is a quarter-mile paved oval.

The track was converted to a half-mile paved oval in 1957, when its began to be a NASCAR series track. The speedway was lengthened between the 1969 and 1970 seasons. The corners were cut down from 35 degrees to their present 18 degrees in 1972. The track was repaved between the 1995 and 1996 seasons.

Track History
The track first featured "horseless carriages" and motorcycles on June 11, 1904 on a 1 1/8 (1.125) mile dirt oval. Races were canceled after a motorcycle ran in to the back of a car that was lining up. Harness (horse) racing events were also held at the track.

In September 1904 another series of races was organized. Most of the entrants came directly to Nashville from the 1904 World's Fair in St. Louis, Missouri. Racing pioneer Barney Oldfield was one of the entrants. People marveled at cars driving over 60 miles per hour (100 kilometers per hour).

The track began holding annual events in September 1915 to coincide with the state fair. Many of the same drivers from the Indianapolis 500 brought their cars down to Nashville.

Local tracks sprange up and began running weekly Saturday night shows (collectively called the "Legion Bowl"), and the local racers competed at the track for the 1954 through 1957 State Fairs. In 1958 car racers decided to build a paved racetrack. The racers ended opposition from horse racers by building a horse track. The racers got a 10-year lease from the state fair board in order to build a paved 1/2 mile track which shared the frontstretch with a 1/4 mile track. On July 19, 1958, the first race was held at the new speedway. Races were held only on the 1/4 mile track (except for special events).

The original cars (since 1948) were 1930s model cars called "Modified Specials". By 1964 the parts for cars were too hard to find, so the track changed to newer 1950s model cars called "Late Model Modifieds". Some of the early stars of the track decided to retire.

1960s
The 1960s also frequently brought drivers from outside Nashville, most notably the Alabama Gang. The Alabama Gang (from Hueytown, Alabama) included future NASCAR legends Bobby Allison, Donnie Allison, and Nashville native Red Farmer.

Coo Coo Marlin was the first back-to-back champion in 1965/1966. 1968 champion P.B. Crowell decided to retire, and hired the talented young Darrell Waltrip to drive his car.

Several changes happened at the track in the 1960s. Lights were added to the 1/2 mile track in 1965, and races in the main division moved to the big track. A fire burned the grandstands at the 1965 State Fair. Weekly Tuesday night races were added, and fans were awed by the crazy Figure-8 drivers barely missing each other as they crossed each other's paths. New grandstands were built and the track was lengthened (and banked to 35 degrees) in 1969.

1970s
The bankings in the corners proved to be too fast, so the banking was reduce to 18 degrees. The new ownership decided to hold no weekly races in 1979.

The 1970s also featured talented drivers that would progress to NASCAR's highest division. Second generation drivers Sterling Marlin (son of Coo Coo) and Mike Alexander (son of car owner R.C.) were both track champions. Alabama Gang member Jimmy Means took the track title home to Alabama in 1974 before he moved on to NASCAR.

1980s
In 1980 the track reopened to weekly racing. The new headline division featured smaller Camaro-type bodies called "Late Model Stock Cars". The new division caught on slowly, and only 13 drivers competed in the first race. The division finally caught on in 1987. NASCAR stars that raced in 1987 or 1988 included Bobby Allison, Sterling Marlin, Mike Alexander, Darrell Waltrip, Bill Elliott, and Dale Earnhardt. Third generation driver Bobby Hamilton won track championships in 1987 and 1988.

1990s
The 1990 season was dominated by Jeff Green. Chad Chaffin won the 1993 and 1995 track championships. Andy Kirby won the 1994, 1996, and 1997 track championships before being killed in a motorcycle accident.

The track was renamed "Music City Motorplex" for 2002 by new promoter Joe Mattioli, who's family owns Pocono Raceway and South Boston Speedway.

NASCAR Winston Cup track history
The track held at least one Cup race each year from 1958 to 1984.

A capacity crowd of 13,998 watched Joe Weatherly win the first NASCAR race on August 10, 1958.

Geoff Bodine beat Darrell Waltrip for his second career win in the last Winston Cup race at the track.

NASCAR left the track because the grandstands are too small, and because of a dispute over who would manage the track took place prior to the start of the 1985 season.

Of the 42 Cup races, Richard Petty and Darrell Waltrip are tied for the most wins with eight wins. Waltrip won 5 of 6 races between 1981 and 1984. Waltrip's victory in the 1988 Busch Series event gives him the career best nine wins total at the track. Counting NASCAR, USAC, ASA, and local track races, Waltrip holds the all-time track record for wins with 67.

Busch Series Events
The track held 9 Busch Series races in 1984, 1988, 1989, and from 1995 to 2000. The track was replaced on the schedule by the newly opened Nashville Superspeedway.

Craftsman Truck Series Events
The track held 5 Craftsman Truck Series events between 1996 and 2000. The track was replaced on the schedule by the newly opened Nashville Superspeedway.
