M3

Winchester Services (M3 J8–J9)

Winchester Services sits on the M3 between Junction 8 for the A303 and Junction 9 for the A34 and Winchester. It is run by Moto, and it is the last service area on the M3 before the motorway ends at the M27.

Two sides, and you cannot walk between them

Winchester has separate northbound and southbound sites with no public connection between them. This matters more than it sounds: some facilities are on one side only, so which direction you are travelling decides what you can actually use. Pret A Manger, for example, is listed on the southbound side only, while the Changing Places facility is on the northbound side.

      We check these overhead signs at least every five minutes, but we can't guarantee a sign is still current if an incident or issue has been cleared and the sign has not been updated yet. Signs and news can each carry something the other does not - check both before you travel.

    What is at Winchester Services

    Facilities change, and the split between the two sides is the thing most likely to catch you out. This list was checked on 1 September 2026 against the operator’s own information.

    The traffic around Winchester Services

    The services sit on the quietest measured part of the M3. The stretch from Junction 9 down to Junction 8 carries 56,135 vehicles a day — less than half what the motorway carries at its Southampton end.

    That changes the moment you pass Junction 9. South of it, where the A34 joins, the M3 carries 110,741 vehicles a day — it almost doubles across a single junction, and the lorry share rises from 6.3% to 9.4%. If you are stopping here before continuing south, you are stopping just before the busy half of the motorway starts.

    Service area details are compiled from the operators’ own published information and were last checked on 1 September 2026. Facilities change — if something here is out of date, please tell us and we will correct it.

    M3traffic.co.uk is dedicated to the latest M3 traffic news, checked every five minutes, 24 hours a day. The M3 meets the M25 at M25 Junction 12 — see M25 Traffic, and Traffic News England for traffic news across all of England.
