US 380 is a state highway and is under the control of the Texas Department of Transportation (TxDOT). Although controlled by the state, the portion of the road that is between FM 720/Oak Grove Parkway and Doe Creek is within the Little Elm Town limits. TxDOT controls the speed limit, signal light placement and timing, and construction projects; however, the Town of Little Elm provides law enforcement and traffic control along with the Denton County Sherriff's Office and the Department of Public Safety.
