sentences:  About twelve miles north of the central business district of Cleveland, I-75 curves to the northeast, and crosses the Hiwassee River into McMinn County, and then curves back to the northwest.This area is extremely susceptible to fog hazards, which obscures the visibility of drivers, and several bad accidents have occurred on this section as a result.Running through mostly wooded and agricultural areas, I-75 reaches Athens about 15 miles later, and has an interchange with SR 30, a major east-west corridor in East Tennessee.
