The M3 runs from the M25 at Thorpe down past Basingstoke and Winchester to the M27 for Southampton and the south coast. The smart-motorway section between J2 and J4a carries the heaviest flows, and summer Saturdays add south-coast holiday traffic to the usual commuter pattern. Live incidents, roadworks and closures refresh every 5 minutes.
