Officials with Lucas Oil Speedway have announced that the 13th annual CMH Diamond Nationals will expand to two nights, July 13-14. The USRA Modifieds will run as the support class on July 13, paying $2,000 to win.

The added program and increased purse is to help fill the void of the canceled Show-Me 100 presented by ProtecttheHarvest.com. Efforts to find suitable dates for all the involved series and keep the Show-Me 100 in its original three-day format were not able to be worked out.

Severe weather produced damage to the Lucas Oil Speedway complex on May 20 and forced cancellation of the Show-Me 100, which has been a long-standing Memorial Day Weekend event that's been held at Lucas Oil Speedway since 2010. A rain-out in 2015 forced the final night of the event to be held on Sunday night of Diamond Nationals weekend that year.

The award-winning Lucas Oil Production Studios will be on hand to capture all the action from Lucas Oil Speedway with multiple camera angles, driver interviews, on-board cameras and various technical segments. Additional information including air dates, show times and networks will be announced.

Those who purchased advanced tickets to the Show-Me 100 will receive refunds, as will all those who had reserved camping spots for the Show-Me 100.

All tickets for the Diamond Nationals will be general admission and available at the gate, by calling (417) 282-5984 or online. Admission prices each night will be $30 adults (16 and over), $27 seniors (62 and over)/military, $10 youth (6-15), $70 family pass and FREE (5-and-under). Pit passes will be $40 each night.

For questions about tickets or camping for any event at Lucas Oil Speedway, contact Admissions Director Nichole McMillan at (417) 282-5984 or via email at Nichole@LucasOilSpeedway.com.

Lucas Oil Speedway will re-open on On June 8, as TA/Petro along with KY3 Digital Presents the Big Adventure RV Weekly Racing Series. The Out-Pace USRA B-Mods will headline the action with a $750-to-win, 25-lap main event. The Warsaw Auto Marine & RV ULMA Late Models, Pitts Homes USRA Modifieds and O'Reilly Auto Parts Street Stocks also will be in action. The B-Mods also will run a makeup feature to begin the program, from a May 11 rainout.

Gates will open at 4 p.m. with hot laps at 6:30 and racing at 7:05.
