Stump Cross Interchange

This article is about junction 9A of the M11.
For for other junctions with this name, see Stump Cross.

Stump Cross forms Junction 9A of the M11. Originally the spur ended at a roundabout, but in the 1990s as part of the A11 dualling works between here and the nearby Newmarket Bypass (now part of the A14, then A45) introduced the current dumbbell roundabout arrangement. The B1383 to the south forms the original A11, which was renumbered following completion of the motorway.

The spur itself comes after a 15 mile gap in junctions, which is one of the longest on the motorway network.

1968 proposal

Early proposals for the M11 had it on a different line to what was eventually built. During the late 1960's there were two possible routes running to the west of Cambridge: a line similar to the present route and another running along what is now the A1301, then A130. For the latter the M11 would have freeflowed onto the A130 which would be substantially upgraded to motorway standard and utilise part of the newly built Sawston Bypass which was opened in 1968, the same year this plan was drawn. Despite all this the more westerly route which the M11 now takes was the preferred route at the time.
