Markham Moor is an important junction on the A1 in Nottinghamshire. It handles traffic for the main A1, traffic from Lincoln to Sheffield on the A57 (which multiplexes with the A1 as far as Apleyhead), and Retford traffic on the A638. It also handles local traffic from the B1164 and Markham Moor Service Area.
Before the major upgrades to the A1 in the late 1950s and early 1960s, the A1 Great North Road passed through the junction (then at-grade and staggered), using the now A638 to Retford and Doncaster. The A57 used the other two main arms. In 1957, the A57 to the west was dualled, ending at a roundabout just to the south of the old junction. When the A1 was diverted to meet the new A1(M) Doncaster bypass in 1961, the A1 used this western arm, as happens today. The A1 to the east came later, in 1967.
In 2008 the junction was upgraded to a full Grade-Separated Junction (GSJ) as part of the Blyth - Peterborough works. The junction is now in a standard dumbbell roundabout configuration, and the main A1 traffic flows smoothly through the junction.
For many years, on the approach from the south (locally actually the east-south-east) along the A1, there was an embankment between the separated carriageways as if in preparation for the future construction of a flyover. The layout eventually adopted, with the A1 underneath, was a fairly late change of design; a preferred route had previously been announced that involved the A1 on top. It is generally understood (although I have no confirmation) that the change in design allowed the Little Chef with listed roof to the north of the interchange to be preserved.
