Transportation improvement district

A transportation improvement district (abbreviated TID) or transportation development district (TDD) is a special-purpose district created in some U.S. states for the purpose of coordinating and financing transportation infrastructure improvement programs, particularly road construction projects, among local governments in a specific area. Depending on the state, they may have the authority to levy sales or property taxes or issue municipal bonds. TIDs or TDDs are authorized in Missouri, New Jersey, Ohio, and Virginia.
