The A34 connects the M3 at Winchester with the M4 and M40 at Oxford, carrying port freight from Southampton north and acting as the main route between the Midlands and the south coast. It is dual carriageway rather than motorway, and the Newbury and Oxford sections queue daily. Live incidents and closures refresh every 5 minutes.
