The B3394 was a short link road in the centre of Cosham, to the north of Portsmouth. Owing to the road's short length its history is not fully known. The road was certainly classified by the 1950s but has now been declassified again.
The road started on the High Street in the town centre. This road was originally the A3 but may have become the A333 by the time the B3394 came into being; it is now unclassified and partly pedestrianised. From here the B3394 headed west along Wayte Street to end barely 100 yards later on Northern Road, the original A3 bypass and now the A397.
