The western terminus of SR 662 is at an interchange with Interstate 164 (I-164). From there, SR 662 heads southeast toward Newburgh. The route is a four-lane surface street that has a mix of commercial, business and residential traffic.
Formerly a 4-mile (6.4 km) route that passed through Newburgh, SR 662 connected State Road 66 east of Newburgh with I-164. In recent years, however, the highway was decommissioned through Newburgh proper, and now has a routing of slightly more than a mile from I-164 to Ellerbusch Road on the west side of the town.
