It passes under the railway again, and under the freight line from to Doncaster Railport. At Lindrick Dale, Anston Brook, flowing in from beyond Anston to the west, joins on the left bank. Shortly afterwards, the Brancliffe feeder leaves the river, following an 'S' shaped course to supply water to the Chesterfield Canal near Turner Wood locks. A little further east, it crosses under the Sheffield to Lincoln Line again and through a three-arched aqueduct below the Canal, to pass through Shireoaks. It then loops around the village of Rhodesia, crossing under the Worksop to Nottingham railway line and the A57 Worksop bypass to arrive on the western edge of Worksop. In Worksop, the river was used to power mills for centuries. Three water mills were mentioned in a survey carried out in 1636, one near the present junction of Westgate and Newcastle Avenue, one called Priory Mill, and a third called Bracebridge mill. All had ceased to operate by 1826, but a new water mill had been constructed further to the west, near to the present junction of Newcastle Avenue and the A57 Worksop bypass. It was known as Beard's mill, after its owner Mr. Joseph Beard, and the mill pond was a hive of activity, being used as a skating rink in winter, and for fishing at other times of the year. More exotic activity recorded includes demonstrations of the launching of a lifeboat, and the bathing of elephants when travelling circuses visited the town. The mill building lasted until 1985, when it was demolished to make way for the Worksop bypass. The course of the Ryton through Worksop is largely man-made. It originally flowed much nearer to Castle Hill, probably forming part of the defences, but was diverted in 1842 into a channel further north when the 4th Duke of Newcastle constructed Newcastle Street, in order to develop that part of the town. The river is then culverted as it passes under a shopping complex and the shops of Bridge Street. This section counts as a confined space, and was surveyed in 2007, in a joint venture between the Environment Agency, a team of divers, and Bassetlaw District Council. Some five tons of debris, half a ton of steel, and some stolen goods were removed from the culvert during the exercise. Beyond Watson Road bridge, sluices and extra channels point to the existence of the mill near
