Mid-Ohio Sports Car Course is a road course auto racing facility located in Troy Township, Morrow County, Ohio, United States, just outside of the village of Lexington. (Mid-Ohio has also colloquially become a term for the entire north-Central region of the state, from south of Sandusky to north of Columbus.).
The track opened as a 15-turn, 2.4 mile (3.86 km) road circuit run clockwise. The back portion of the track allows speeds approaching 180 mph (290 km/h). A separate starting line is located on the backstretch to allow for safer rolling starts. The regular start/finish line is located on the pit straight. In 1990, the track underwent a refurbishment. A new retaining Wall was built, the entire track was resurfaced, widened, and Concrete was paved in the apexes of the turns to prevent asphalt deterioration. In addition, a straightaway was paved through the chicane, allowing for two different track layouts, the original 2.4-mile (3.9 km) circuit, and a new 13-turn, 2.258 mile (3.634 km) circuit. In 1990, the CART series began utilizing the 2.258-mile (3.634 km) layout. In 2006, a second major refurbishment saw several improvements. The entire circuit was repaved, and the concrete patches in the turn apexes were removed.
