Heading south from the M27/A27 at Farlington Roundabout along the east side of Portsea Island. After heading past Portsmouth City Airport (since redeveloped), it would bridge over Milton Lake (an inlet of Langstone Harbour, now reclaimed and the area developed) and head along the route of a narrow and disused canal to Milton, where there would be a junction at the east end . From there it would run along Goldsmith Avenue and Winston Churchill Avenue as an elevated D3 viaduct (above the D2 roads), interchanging with the inner ring road at Bradford Junction, and the N-S Route (M275) at St Michaels.
The A2030 follows the route to Milton Lake, where it simply goes along what was then the coastline. While this pre-existed the motorway plans, it was widened where it was on the line of the motorway. The only other evidence of the motorway on the ground is that Winston Churchill Avenue is slightly below grade and has a wide alignment, allowing the possibility of a D3 viaduct above.
