Topeka ? Kansas Speedway and a competitor are joining forces to push a single proposal for a state-owned casino at the NASCAR track in northeast Kansas.

The announcement came Thursday from Penn National Gaming Inc., of Wyomissing, Pa., and International Speedway Corp., parent company of the track.

Penn had been pursuing its own bid for the contract to build and manage a state-owned casino near the speedway in Wyandotte County.

International Speedway Corp. had been partnered with The Cordish Co. of Baltimore in a proposal to bring a casino to the No. 2 turn of the speedway in Kansas City, Kan. But Penn and ISC said Cordish was selling its interest to Penn.
