Foynes (ˈfɔɪnz; ) is a town and major port in County Limerick in the midwest of Ireland, located at the edge of hilly land on the southern bank of the Shannon Estuary. The population of the town was 520 as of the 2016 census. Foynes as a port has a long history, being first surveyed in 1837, and is now the location of a major deep water seaport operated by the Shannon Foynes Port Company, an amalgamation under the Harbours Act 2000 of the agencies operating the ports of Limerick and Foynes. It is anticipated that more traffic from the upstream Limerick Port will ultimately be diverted there as the latter portlands are redeveloped as commercial and residential properties. A railway line to Limerick via Patrickswell and Raheen is in existence but not operational. Iarnród Éireann's policy of concentrating on what it sees as more profitable passenger operations means the Port's traffic is entirely served by road. Foynes Port Company was amalgamated with the Shannon Estuary Ports Company (which had responsibility for the other areas of the Estuary) in 2000, to form Shannon Foynes Port Company (SFPC). SFPC is the second largest port facility in Ireland, handling over 10 million tonnes of cargo annually through the six terminals currently operational. Planning permission has been granted for an LNG import terminal at Ballylongford, County Kerry, within SFPC's jurisdiction; once constructed it will add considerably to throughput. During the late 1930s and early 1940s, land-based planes lacked sufficient flying range for Atlantic crossings. Foynes was the last port of call on its eastern shore for seaplanes. As a result, Foynes would become one of the biggest civilian airports in Europe during World War II. Surveying flights for flying boat operations were made by Charles Lindbergh in 1933 and a terminal was begun in 1935. The first transatlantic proving flights were operated on 5 July 1937 with a Pan Am Sikorsky S-42 service from Botwood, Newfoundland on the Bay of Exploits and a BOAC Short Empire service from Foynes with successful transits of twelve and fifteen-and-a-quarter hours respectively.
