M3 Overhead Signs
This page shows what the M3 overhead signs are displaying right now — the electronic message signs National Highways use to warn drivers about closures, queues, hazards and journey times. They are listed junction by junction, in the direction of travel, for both carriageways.
Each message shows when National Highways last set it and how long ago. Signs can warn about a road ahead, so a message may be about a road you join later. We take road-closed messages off this page 12 hours, and other messages 2 hours, after National Highways last set them.

Checked 20:52 (8:52pm) Fri 30 Oct 2026 Each message shows when National Highways last set it, and how long ago.
Two kinds of traffic information. This page shows what the overhead message signs on the M3 are displaying. Our latest traffic news shows National Highways’ incident and roadworks reports. Each can carry something the other does not, so we show both and label which is which - check both before you travel.
⚠ Our last check of the overhead signs was more than an hour ago, so we have hidden the sign messages until we check again.

About the M3 overhead signs
The messages on this page come from National Highways’ own feed of the electronic signs above and beside the M3. We show them exactly as National Highways set them. A sign can be switched to a new message at any moment, so always follow the signs you can see on the road. For accidents, closures and roadworks see our Latest M3 Traffic News page.
