SR 232 functions as a spur from the Interstate into the western part of the independent city of Radford.
SR 232 begins at an interchange with I-81 just east of the Interstate's bridge over the New River just south of Radford in Montgomery County.
SR 232 heads straight north as the main commercial street of the city.
The state highway gradually curves to the northeast before reaching its northern terminus at US 11.
Main Street continues east as US 11 toward the eastern part of Radford; US 11 also heads north as Lee Highway to cross the New River into Pulaski County.
