M27 Junction 10 Upgrade Set to Open Early.
A major boost for Hampshire drivers is on the way, with the M27 Junction 10 upgrade confirmed to be opening months ahead of schedule.
According to the BBC, the new junction expected to carry around 30,000 vehicles a day will begin phased opening from 14 September.
Key features include new slip roads, four roundabouts, and a 60m underpass installed using a Christmas “box slide” operation.
The project, costing over £100m, was originally due to open in winter 2026.The westbound off‑slip, underpass and roundabouts will open first, with remaining on‑slips following later in the autumn.
Temporary 50mph limits between junctions 9 and 11 will stay in place until safety testing is complete.
