The Indianapolis Motor Speedway has agreed to update its facilities to comply with the federal Americans with Disabilities Act.
Among the changes will be the addition of wheelchair seating in the grandstands, making bathrooms wheelchair accessible and adjustments to parking.
Speedway officials said Thursday the timetable for the changes is two and a half years.
In 1999, Dan Ward attended a practice session at IMS and said he was denied access to the pits because he was in a wheelchair, even though he had a pit pass. He took his concerns to the U.S. Attorney's office, and an investigation found 360 different ADA violations.
The Speedway was built in 1909. The original ADA standards were adopted in 1991 and updated in 2010.
