M3 Traffic Reports and Updates

For M3 traffic reports, use our dedicated M3 website. National Highways records the M3 as eastbound and westbound rather than north and south, so the site does the same: eastbound is towards London, westbound towards Southampton.

Where to Find M3 Traffic Reports Now

Go to our M3 traffic news page for every current report, or straight to the page you need:

• the latest M3 traffic news
• accidents and incidents
• roadworks
• what the overhead signs are saying
• the variable speed limits in force now
• separate eastbound (towards London) and westbound (towards Southampton) pages
• closures tonight
• the M3 services
• M3 junction maps

Each report says where the problem is, which way it affects, and when National Highways expects it to clear, so you can decide quickly whether to change your plans.

For facts about the road itself, its length, route and junctions, see about the M3 motorway.
