The B3347, a mile south of Ringwood.
The B3347 runs along the Avon Valley in south west Hampshire, and is mostly on the line on the former A338.
It starts from a roundabout at Purewell on the A35 Christchurch Bypass and goes underneath the main Southampton - Bournemouth line through Burton to Winkton. From here, it passes through more open country through Sopley and Avon along the flood plain of the river, briefly entering the New Forest National Park at Bisterne. Beyond this, it heads back into the edge of Ringwood, which it follows into the town centre. There's then a brief section of dual carriageway, and a grade separated roundabout with the A31. The A338 resumes its course straight ahead.
The B3347 was originally created around 1st April, 1925, and linked the A35 to what was the A338 at Winkton.
In the 1970s, after the construction of the A338 Wessex Way, it took over the old route of the A338 north from this point as far as Ringwood.
