Small Sheridan has big goals when it comes to transportation. Originally known as Aviation Field, Sheridan's County Airport functioned mainly as mail and entertainment transportation for years, and now provides daily air transportation for Sheridan's residents. It currently boasts the largest aircraft traffic of any private airport in the state of Wyoming. The city's convenient location near Interstate 90 makes ground transportation and easy option for travelers as well. Ground options for transportation include multiple bus lines, including the Jefferson Bus Line and Arrow/Black Hills Stage Line.
