History
A short culverted section of the Sough Dike outfalling in to the River Don, in Oughtibridge, near Sheffield. The infall has concrete reinforcement but the primary construction is stone. The water has worn a channel through the middle with many holes and water leaking in from all sides. Erosion is so bad that in the middle there is a large pool too deep to pass.

History
The tunnel was built in 1849 for the South Yorkshire, Doncaster and Goole Railway Company. The head engineer was Charles Bartholomew of the River Don Company. It consists of Gritstone voussoirs and rock-faced sandstone walling. Quoined buttresses flank a horseshoe arch with rustication below the impost band and roll-moulded hoodmould. Roll-moulded cornice breaks forward over the buttresses; blocking course steps up at centre. The line was opened on 10th November 1849 and linked the Midland and Great Northern networks; after 1864 it became part of the Manchester, Sheffield and Lincolnshire railway which itself became the Great Central Railway in 1897.

History
It was here that ICI manufactured sodium carbonate (soda ash) and its various by-products such as sodium bicarbonate (bicarbonate of soda), and sodium sesquicarbonate. The Winnington site, built in 1873 by the entrepreneurs John Tomlinson Brunner and Ludwig Mond, was also the base for the former company Brunner, Mond & Co. Ltd. and, after the merger which created ICI, the powerful and influential Alkali Division. It was at the laboratories on this site that polythene was discovered by accident in 1933 during experiments into high pressure reactions.
Wallerscote was built in 1926, its construction delayed by the First World War, and became one of the largest factories devoted to a single product (soda ash) in the world. However, the decreasing importance of the soda ash trade to ICI in favour of newer products such as paints and plastics, meant that in 1984 the Wallerscote site was closed, and thereafter mostly demolished. The laboratory where polythene was discovered was sold off and the building became home to a variety of businesses including a go-kart track and paintballing, and the Winnington Works were divested to the newly formed company, Brunner Mond, in 1991. It was again sold in 2006, to Tata (an Indian-based company) and in 2011 was re branded as Tata Chemicals Europe. The Winnington plant closed in February 2014, with the last shift on 2 February bringing to a close 140 years of soda ash production in Northwich.
