|Junctions related to the A331|
Frimley Interchange is junction 4 of the M3.
Original plans for the M3 from the late 1960s show a Roundabout interchange at the former A321, now B3411. The junction was never built here nor to this design. Instead a different junction was built half a mile to the west.
When the M3 opened here in 1971, neither the A331 Blackwater Valley Route nor the A325 Frimley bypass existed. The northern roundabout of the interchange was not yet built: the carriageways under the motorway were part of the slip roads to and from the London-bound M3, and had motorway status. From the interchange's southern roundabout, a dual carriageway all-purpose link ran 500 yards south to an at-grade roundabout on the then A325 Frimley High Steet / Farnborough Road.
The business park is also a later addition.
