The Thurcroft Interchange is a large motorway junction in South Yorkshire (the Metropolitan Borough of Rotherham).
The draft scheme for the 87 miles from Crick to Doncaster was first published on 8 January 1960, where the extension to Leeds was now north of the Aston Interchange; all the junctions shown are those that would be built.
South of the interchange, the Barlborough to Thurcroft 7.2-mile £4.56m contract was awarded to Tarmac Civil Engineering Ltd in October 1965.
At this time, 37 miles of the M1, north of Crick, were open to Kegworth Interchange (junction 24) from December 1965, and the M18 was expected to be built in two years.
The prestressed concrete beams for the section of the M1 from junctions 31-34 were made by Dow-Mac at Tallington in Lincolnshire.
