Michigan International Speedway

Groundbreaking took place on September 28, 1967. Over 2.5 million cubic yards (1,900,000 m³) of dirt were moved to form the D-shaped oval. The track opened in 1968 with a total capacity of 25,000 seats. The track was originally built and owned by Lawrence H. LoPatin, a Detroit-area land developer who built the speedway at an estimated cost of $4–6 million.[3] LoPatin was President of American Raceways and had a controlling interest in Trenton Speedway, Texas World Speedway and Riverside International Raceway until the company went bankrupt in 1971. Financing was arranged by Thomas W Itin. Its first race took place on Sunday, October 13, 1968, with the running of the USAC 250 mile Championship Car Race won by Ronnie Bucknum.

In 1972, Roger Penske purchased the speedway for an estimated $2 million. During Penske's ownership the track was upgraded several times from the original capacity to 125,000 seating capacity. From 1996 to 2000, the track was referred to as Michigan Speedway. This was to keep consistency with other tracks owned by Roger Penske's Motorsports International before its merger with ISC.[3]

In 1999, the speedway was purchased by International Speedway Corporation (ISC) and in 2000 the track was renamed to its original name of Michigan International Speedway. In 2000 10,800 seats were added via a turn 3 grandstand bringing the speedway to its current capacity. In 2004-2005 the largest renovation project in the history of the facility was ready for race fans when it opened its doors for the race weekend. The AAA Motorsports Fan Plaza—a reconfiguration of over 26 acres (110,000 m²) behind the main grandstand. A new, three-story viewing tower housing the Champions Club presented by AAA and 16 new corporate suites targeted VIP guests, while a press box and a race operations facility high above the two-mile (3.2 km) oval welcomed the media and race officials.[3] Michigan was repaved prior to the 2012 season. This marks the first time since 1995 that the oval was resurfaced, along with 1967, 1975, and 1986. Also new for 2012 was the addition of a new 20-space trackside luxury campsite to be known as APEX. Situated in turn 3, each site will offer a 20-by-55-foot (6.1 by 16.8 m) area. To accommodate these new campsites, the remaining silver grandstands in turns 3 and 4 were removed.[4]

On January 28, 2019, it was revealed on ISC's 2018 annual report that the speedway's track seating was reduced from 71,000 to 56,000.[1]

• August 1985: During practice for the Michigan 500, polesitter Bobby Rahal crashed hard into the wall, an accident blamed on the newly introduced Goodyear radial tires. Competitors refused to race the following day, and the race was postponed. The following weekend, just 10 of 30 cars finished the race, 10 due to mechanical failures and 10 due to wrecks. Danny Ongais flipped several times down the backstretch while Mario Andretti broke his collarbone and hip, and had to miss the next race.

Emergency workers at the track extricated him from the car, and he was immediately airlifted to Saint Joseph's Hospital in Ann Arbor, Michigan. He was diagnosed with critical brain and lung injuries and given only a 10% chance of surviving the night. After making a full recovery, Irvan returned to NASCAR in 1995. In 1997 Irvan won his final race at the June race at Michigan. Exactly 5 years after his near fatal accident there, Irvan crashed at Michigan while driving his own #84 Irvan-Simo Federated Auto Parts Pontiac in a practice session for the Busch Series race. Ernie was again airlifted from the track and was diagnosed with a mild head injury and a bruised lung as a result of the accident.
