The Street Department has a diversity of responsibilities. These include paving, repair and maintenance of 70 miles of roads; storm sewer maintenance; erecting and maintaining signs; debris removal and grass cutting on all rights of way; garbage collection; yard waste and leaf collection; snow removal; animal control and a garage for maintenance of town vehicles. This is accomplished with a crew of 28 people plus two administrators, a secretary and a dispatcher.

The 1989 annexations stretched the capabilities of the department, so garbage collection in the annexed areas is contracted out. However, all other areas of responsibility fall to the Street Department. Clarksville's Street Department has also carried out some small road construction projects, providing significant savings to the town.

The Street Department has the most visible impact on Clarksville residents and visitors and receives frequent praise for the good service provided.
