The Levine Children's Hospital on Friday received a $350,000 donation from Speedway Children's Charities.
The donation is part of a $60 million fundraising campaign that began in 2004, when Sandra and Leon Levine gave $10 million to start work on the hospital.
The project, which will be completed in October, will cost $85 million.
Marcus Smith, executive vice president of Speedway Motorsports, said Speedway Children's Charities, the charitable arm of the organization, usually gives to smaller groups that help children, but that this hospital will help take some of the workload off the smaller organizations.

"It's a hometown thing," Smith said. "It's an opportunity to give to a world-class facility."
In honor of the donation, the facility's family lounge will be named for Speedway Children's Charities.
