London to Southampton motorway. Confusingly referred to as Exeter Radial in early documentation, though this was because it followed the A30 corridor, rather than any plan for the motorway to reach Devon. It also only partially forms the zone boundary between motorway zone 2 and motorway zone 3, with the section south of junction 8 being within zone 2.

Junctions

Thorpe Interchange

Main Article: Thorpe Interchange

Thorpe Interchange, Surrey is the name of the junction between the M3 and M25 motorways. It is of a whirlpool design, and the M3 is has a lane painted out through the junction, which although it decreases the capacity through the junction actually helps the interchange move more freely due to the amount of interchanging traffic here.

Services

Fleet services

Main Article: Fleet services

Fleet services were for a long time the only services on the M3, and are located in a forest environment. The services did not open with the motorway, although the footbridge across the motorway was.

Winchester services

Main Article: Winchester Services

Winchester services opened in 2001 and are located between junctions 8 and 9. Unusually for a 21st century MSA, it is located on two sites, one for each direction, but less unusually are quite some distance from the named town, in this case Winchester. There is also no connection between the two sites, meaning that northbound traffic wishing to stay at the hotel must detour via junction 7.
