I-40 Motocross

I-40 Motocross in Lenoir City is closed. The property was converted to asphalt plant operations. During operating years, I-40 MX was a historic supercross-style track on 30 acres just off I-40, operating continuously from 1981, with Saturday-night races April through October. The 1981-to-recent operating heritage made I-40 Motocross one of East Tennessee's longest continuously-operating motocross facilities during operating years. Notable championship-level riders Mike Brown and Damon Bradshaw came through the facility during their development pipeline, the kind of pro-rider connection that genuinely defines heritage motocross facility cultural identity. The supercross-style design philosophy during operating years built technical-features density that pure outdoor motocross facilities can't match. The Saturday-night race programming under lights extended the operating window past sunset, the kind of evening-race programming that builds destination event identity. The closure ended one of East Tennessee's heritage motocross facility identities. The conversion to asphalt plant operations means the motocross property has been physically transformed rather than just shut down, no possibility of reopening at the same location. For local riders who used I-40 Motocross as their home destination, active alternative facilities in the broader East Tennessee region include: Mountain Motocross in Madisonville, the Mark Barnett-designed facility with the 1.8-mile gated track on 100 semi-wooded acres at the Tellico Mountains foothills. I-81 Motorsports Park in Greeneville, the multi-discipline 400-acre facility with five distinct riding surfaces including a lighted pro motocross track. Shiloh MX Park in Seymour, a regional East Tennessee motocross facility. For local riders in Loudon County and the broader East Tennessee region seeking active motocross facilities, refer to the broader East Tennessee regional motocross listings for current operating windows and access details. The property is retained in this directory for historical reference and to preserve the regional motocross record. The 1981 heritage closure marked the end of a 40+ year East Tennessee racing institution.
