The B&L Transport 170 was a NASCAR Xfinity Series race that was held at Mid-Ohio Sports Car Course in Lexington, Ohio, United States. The inaugural event took place on August 17, 2013, and was scheduled to be contested for 90 laps over a distance of 203.22 miles (327.05 km). However, the race was extended by four laps due to a green–white–checker finish. In 2015, the race was reduced to 75 laps (169.35 miles).
The 2016 race saw the fourth time the Xfinity Series used rain tires in a points event; the previous times were Road America in 2014 and Montreal in 2008 and 2009.
In 2022, Mid-Ohio was taken off the Xfinity series schedule, in exchange for Portland International Raceway. The track was then given a NASCAR Camping World Truck Series race.
