M18 motorway (Great Britain) M18 motorway (Great Britain) The M18 is a motorway in Yorkshire, England. It runs from the east of Rotherham to Goole and is approximately long. A section of the road forms part of the unsigned Euroroute E13. The M18 runs in a north east/south west direction from junction 32 of the M1 motorway to junction 35 of the M62 motorway. It passes east of Rotherham, southeast of Doncaster and Armthorpe, and west of Thorne. It meets the A1(M) at junction 2 (A1(M) junction 35)--known as the Wadworth Interchange—and the M180 motorway at junction 5. Access to Doncaster is provided from
M1 motorway carried by bridge but no longer reaches the northbound carriageway as it is cut off by the motorway continuing south. The final section of the M1 was opened to Junction 1 at Staples Corner in 1977. There the motorway meets the North Circular Road (A406) at a grade separated junction and roundabout. Unrealised plans made in the 1960s would have seen the motorway continue through the junction on an elevated roadway to end at West Hampstead where it would have met the North Cross Route, the northern section of the London Motorway Box, a proposed ring of urban motorway around
