A397 Portsmouth – Cosham

Looking south on the A397 towards the railway bridge

The A397 is the former A3 through Cosham, Hampshire. Plans to extend it north through Waterlooville to reach Junction 1 of the A3(M) were never executed.

Beginning at the Portsbridge Roundabout there's a short bit of dual carriageway, before a junction with the original road through Cosham. Over the railway the road is a reasonably wide S2, but it widens out to D2 on returning to ground level. Almost immediately, there's a roundabout, and then another short bit of D2 before the road ends at Spur Road Roundabout.

parallel A roads in Cosham on OS 7th Series mapping

The history of this route is debatable. The original A3 through Cosham typically appears on old OS mapping as an A-road along with the newer Northern Road (currently A397 but apparently the A3 from the 1930s at the latest) running parallel.
