About this road

The A3 at a glance

The A3 links London with Guildford and Portsmouth, running motorway-standard for long stretches. The Hindhead Tunnel removed its worst bottleneck, so today's delays cluster around Guildford and the M25 interchange at Wisley. Live incidents and closures refresh every 5 minutes.
