Welcome to the Tennessee Department of Transportation! Transportation is so basic that many of us overlook its overwhelming importance in our daily lives. Practically everything used in our homes, offices or schools across Tennessee - from furniture to food items to clothing - requires a large and complex transportation network. The Department of Transportation provides citizens of Tennessee and travelers with one of the best transportation systems in the country. TDOT consistently wins awards for its projects, highway design and innovative approach to transportation. Since 1998, Tennessee was voted as having one of the top five highway systems in the country by a national trade magazine. TDOT is a multimodal agency with responsibilities in aviation, public transit, waterways, railroads and cycling and walking. Our involvement ranges from airport improvements to funding transit buses to planning for river ports. The Department of Transportation has approximately 3,400 employees with four statewide region facilities in Jackson, Nashville, Chattanooga and Knoxville. TDOT headquarters is located in downtown Nashville.
