"Property management" in the highway transportation context refers to the administration of property acquired for highway purposes to ensure that the public interest is served. The properties that State Departments of Transportation (SDOTs) oversee are valuable resources that need to be managed in order to safeguard the safe and efficient functioning of highway improvements and their related facilities. For that reason, each SDOT has the responsibility to maintain, lease, or sell its properties and to keep an inventory identifying where such lands are located.
