Ower Interchange

Ower Interchange is junction 2 of the M27.

It originally consisted of a roundabout with a motorway to the north, the number of which is disputed - A36(M) being the alleged number, though all the evidence points to it being an M27 spur. One source suggests that the plan was to number it M270.

The A326 Totton western bypass was added to the junction in the late '80s, downgrading the roundabout and spur to A36. Prior to this being built, the stub of a link road left the roundabout and headed south-east. Despite the roundabout being under motorway regulations at the time, the link road was single carriageway. It is possible that this was always intended to be used by the maintenance compound, which was built in 1975.
