Miller Motorsports Park plans to cease operations on October 31, 2015, according to the facility's website, which posted a short statement late last week.

"On behalf of my family, I would like to thank all of those who have supported the track over the years, both locally and worldwide, for their enthusiasm and use of the facility," Gail Miller, owner of the Larry H. Miller Group of Companies, wrote on the Miller Motorsports Park site.

The 500-acre motorsports park in Tooele, Utah, opened in 2006, and has hosted a number of races, driving schools, and private events throughout the years.

"This is a huge disappointment," Tooele County Commissioner Shawn Milne told The Salt Lake Tribune. "The racetrack is top notch, and we appreciate the tourism it brings in."

The American Le Mans Series and GRAND-AM Rolex Series both held races there through 2010; the Pirelli World Challenge crowned its champions there last year and will hold an all-class weekend in August later this year.

In addition, the facility will still hold all racing events, driving schools, karting events, and other activities planned for this summer.
