Gailey Interchange

This article is about the junction between A5 and M6 to the north of Wolverhampton.
For the often confused junction between A5 and A449 to the west, see Gailey Island.

The eastern side of the roundabout

Gailey Interchange is a roundabout interchange located to the north of Wolverhampton and west of Cannock, Staffordshire, and is junction 12 of the M6 motorway.

For southbound traffic, it is the northernmost exit for both Wolverhampton and Cannock, whilst for northbound traffic it is signed for Telford, though the majority of traffic from the south will have exited at junction 10A and used M54.

Whilst known as Gailey Interchange, it is named after the hamlet of Gailey a mile or so to the west, and is rather confusingly similar to Gailey Island, which is the junction of A5 and A449 in the hamlet itself.

The junction is unchanged from its original opening in March 1966.

It has the alternative name of Calf Heath Roundabout (used by Staffordshire County Council), despite being some way and not directly accessible from the village of Calf Heath. It is exclusively locally known as Gailey Interchange however.
