Over the years, transportation has been the key to the development and growth of Presque Isle and Aroostook County. At first, the only way into the area was to travel through New Brunswick via the St. John River in Durham boats. In the 1830's the Military Road was built from Bangor to Houlton and later to points north. The New Brunswick Railway came to Presque Isle in 1881 followed by the Bangor and Aroostook Railroad in 1894. In the mid-1930's the Presque Isle Airfield was developed.
