 Although Bristol's economy no longer relies upon its port, which was moved to docks at Avonmouth during the 1870s and to the Royal Portbury Dock in 1977 as ship size increased, it is the largest importer of cars to the UK. Until 1991, the port was publicly owned; it is leased, with £ 330 million invested and its annual tonnage increasing from 3.9 million long tons (4 million tonnes) to 11.8 million (12 million). Tobacco importing and cigarette manufacturing have ceased, but the importation of wine and spirits continues.
