KANSAS CITY, Kan. — There are more changes in the works at Kansas Speedway.

Officials received the final layout from their design team this week for a proposed road course through the infield, and construction is scheduled to begin after the April race.

Track president Pat Warren also said Friday that he hopes one of the two Sprint Cup races at Kansas Speedway will be run at night in 2013. The track installed lights last year and drew about 25,000 fans last fall for an ARCA race run under the lights.

The infield road course will be built in conjunction with a reconfiguration and repaving of the original 1½-mile tri-oval. The work will be finished before the October race weekend.

The track will host its first Grand-Am race on the road course next year.
