Plans are being made for the similarly slow run from London to the West and Southampton.

Original plan for Sunbury Cross from the mid-1960s with an additional roundabout for Ringway 3. This layout was later abandoned as most of the turning traffic would be funnelled onto the C/D lanes between the two roundabouts which would have limited capacity. This plan also shows Ringway 3 meeting the roundabout at-grade.
Freeflow design for the M3/Ringway 3 junction at Sunbury as an improvement to the originally proposed two roundabout junction. The roundabout at M3 J1 would have east facing slip roads only to encourage traffic onto Ringway 3 rather than the A308. It was also felt unnecessary to have connections between Ringway 3 and the M3/A316 into London.
An alternative layout for the M3/Ringway 3 junction at Sunbury Cross following the decision to abandon the original two roundabout plan.
