cars. The docks were expanded in 1908 with the construction of the Fish Dock, accessible through Wyre Dock and still used today for the inshore fleet. Plans for a pier were first made in the 1890s but building did not start until 1909 and it was opened in 1910. It was the last new seaside pier to be built in the United Kingdom. 20th century By the 1920s, the fishing industry was at its height, employing over 9,000 people. Over the next few years, the sea front along the north shore was developed in resort fashion, to encourage visitors for whom the brashness of Blackpool was too daunting. The Marine Hall entertainment complex (1935), golf course (1931) and Model Yacht Pond (1932) all date from this era. In the 1920s, the salt works, by now owned by the United Alkali Company (after 1926 part of ICI), was considerably expanded, and became an ammonia-processing plant. ICI built an adjacent chemical processing plant, known as ICI Hillhouse. ICI would become the town's third-largest employer, after the fishing and tourism industries. The first fully automated telephone exchange in Britain was put into operation to serve the town on 15 July 1922. The town was hit by a huge flood in October 1927, which put 90% of the area of the town under water. Only the higher lying areas around the Mount escaped. Additional housing was built in the 1920s and 1930s in the less developed central areas of the town, and a further development boom occurred in the 1960s in the lower lying western portion of the town (Larkholme). Many industries related to fishing grew up along the rail corridor on the eastern side of the town, and a number of unrelated industries also moved to the area to take advantage of the availability of labour. By the 1960s, however, Fleetwood began to decline economically. The last ferry to the Isle of Man sailed in 1961. The sailings have been revived periodically since. The main railway station was closed in 1966 as a result of the Beeching cuts, and the passenger terminus was moved to Wyre Dock railway station. This in turn was closed in 1970, as the branch line from Poulton was taken out of service. Additional light industry developed along the former railway bed. The rise of package holidays abroad led to fewer visitors generally to British resort towns. As Blackpool
