the route of the proposed canal away from Salford and across the Irwell into Manchester. A second Act was secured for this variance, which included an aqueduct to cross the Irwell. This was built relatively quickly for the time; work commenced in September 1760 and the first boat crossed on 17 July 1761. The canal opened in 1761 and along with the stone aqueduct at Barton-upon-Irwell, was considered a major engineering achievement. One writer said that when finished, it "will be the most extraordanary thing in the kingdom, if not in Europe. The boats in some places are to go underground, and in other places over a navigable river, without communicating with its waters ..." Worsley Delph, now a scheduled monument, was the entrance to the Duke's underground mines. Two entrances, built years apart, allowed access to the Starvationer boats, the largest of which could carry of coal. The entrances allow access to of underground canal on four levels, linked by inclined planes. The burgeoning village became a hub of commercial activity. The Duke employed craftsmen to service a wide range of industries including boat-making, plastering, blacksmithing and mining. A local quarry supplied limestone, for which a kiln was constructed at the junction of Barton Road (B5211) and Stableford Road. A quarry at the Delph supplied building materials for the region, including the stone used to construct Brindley's aqueduct. To accommodate the workers needed for these industries the Duke built extra housing and cottages. In a diary entry of 1773, Josiah Wedgwood wrote of the area "We next visited Worsley which has the appearance of a considerable Seaport Town. His Grace has built some hundreds of houses, & is every year adding considerably to their number." Worsley Green became a thriving centre of industry. With the death of the Duke in 1803, his estates were inherited by his nephew, George Leveson-Gower, who later became the Duke of Sutherland. The canal and coal estates were placed under the control of the Bridgewater Trust, and in 1833 the rest of the estates were inherited by the Duke of Sutherland's son, Francis Leveson-Gower who changed his surname to Egerton, and in 1846 became the Earl of Ellesmere. The mines ceased production in 1887, and with the expiration of the Bridgewater Trust in 1903 the village began to change; the Duke's warehouse and the works on what is now Worsley Green were demolished.
