|Route outline (key)|
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 heads north, going underneath the main Southampton - Bournemouth line through Burton to Winkton. From here, it passes through more open country through Sopley, where there is a one-way loop along the narrow streets, and Avon along the flood plain of the river of the same name. The road briefly enters the New Forest National Park at Bisterne. Beyond this, it continues on to Ringwood, running 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.
