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 Aberford. The new road involved the construction of a series of new junctions, bridges and viaducts to the east of Leeds. When the new section of M1 was completed and opened on 4 February 1999, the Leeds South Eastern Motorway section of the M1 was redesignated as the M621 and the junctions were given new numbers (M621 Junctions 4 to 7). The M1 was extended south from its original starting point at Junction 5 towards London in three stages. The first stage, opened in 1966, took the motorway south-east, parallel to the A41 to meet the A5 at junction 4
