Achill Island in County Mayo is the largest island off the coast of Ireland, and is situated off the west coast. It has a population of 2,700.  Achill is attached to the mainland by Michael Davitt Bridge, between the villages of Gob an Choire (Achill Sound) and Poll Raithni. A bridge was first completed here in 1887, replaced by another structure in 1949, and subsequently replaced with the current bridge which was completed in 2008.  Source
