The M180 South Humberside Motorway connects from the Tudworth Hall Link Road (A18(M)), which was built under the Hatfield-Thorne Contract, to the A18 South of Scunthorpe at Bottesford Moor.
From this point the Motorway runs South of Scunthorpe and to the North of Brigg where it connects to the Humber Bridge via an improved Trunk Road, A15. The route continues, as the A180, to Grimsby, Immingham and the East coast.
The completion of the M18 provided a link between the M1 near Rotherham and the M62 near Goole with connection to the M180. This completed the Motorway 'box' between the industrialised centres of West and South Yorkshire and Lancashire, the East Coast 'Euroports' and the nation's Motorway system. It is divided into eight contracts.
