Casco Bay Island Transit District, also known as Casco Bay Lines, operates passenger, vehicle and freight service year-round. Casco Bay Lines ensures that passengers have safe, dependable and reliable transportation, and is considered the “lifeline” for the residents of the islands. Casco Bay Lines’ ferries transport nearly one million passengers, 30,000 vehicles and 5,300 tons of freight annually. Casco Bay Lines also delivers the U.S. mail and transports island students to and from Portland. A wide range of scenic cruises and charter trips for celebrations, meetings and sightseeing are available as well.
Casco Bay Island Transit District (CBITD) is a body corporate and politic created under State Enabling Legislation in 1981 to serve residents and visitors of six Casco Bay islands: Peaks Island, Little Diamond Island, Great Diamond Island and Cliff Island (which are within the City of Portland), and the Towns of Long Island and Chebeague Island. The CBITD Board is composed of 12 Directors — 10 elected from the islands, one appointed by the City of Portland, and one appointed by the Commissioner of the Maine Department of Transportation.
