1840s, to the haddock grounds of the North Atlantic Ocean. At this time, all the fishing vessels out of Fleetwood were sail-powered fishing smacks, few being over 40 tons deadweight. The Fleetwood Docks Act of 1864 enabled the construction of a dock and embankment for both fishing and general cargo. Work on what was to become Wyre Dock began in 1869 but was suspended for financial reasons. A second Act in 1871 gave construction authority to the Lancashire and Yorkshire Railway Company, under chief engineers Sir John Hawkshaw and Harrison Hayter. Construction itself, by John Aird & Sons, was completed in 1877. Heavy industry came to the area in the late 1880s with the construction of a salt-processing works on the southeastern edge of the town by the Fleetwood Salt Co. Ltd, using salt mined in Preesall, across the river. By the early 1890s, the construction and expansion of rival cargo ports in the North West and the building of the Manchester Ship Canal heralded the decline of Fleetwood's prominence as a cargo port. However, at the same time this was more than offset by a period of rapid expansion of the fishing industry, signalled by the launch in 1891 of the first steam powered trawler, the Lark. All the other major fishing ports in Britain, Hull, Grimsby and Aberdeen, were on the east coast, so there was a competitive advantage for a west-coast port with good rail links. By the start of the 20th century, Fleetwood's position as one of the three major fishing ports in England was cemented. James Marr brought a fleet of steam trawlers to Fleetwood and actively started to change the port by selectively fishing for hake, which until then had been treated as a much less desirable catch. Many of the houses in the old area of town around the Mount and Lord Street were built in the 1890s. In keeping with the thriving economy, these terraced houses were large for their era. An electric tramway link to Blackpool was constructed in the 1890s and remains operational to this day. The trams were routed along East Street and West Street (now Lord Street and North Albert Street) rather than Dock Street, and commercial trade followed, making those streets the commercial centre of the town. Fleetwood is the only town in Britain with trams running the full length of its main street, sharing road-space with
