M27 Junction 10 reaches major milestone with phased opening from 14 September.

The M27 Junction 10 improvement scheme will start to open to traffic in phases from 14 September 2026.

The first phase will see the new westbound off-slip road, motorway underpass and four new roundabouts brought into use. The new westbound off-slip road will provide access from the M27 westbound for traffic travelling from the Portsmouth direction to the new carriageway and underpass, and this will replace the existing junction 10 westbound off-slip loop. The new dual carriageway (to be known as the A32/A3222 link road) through the underpass will initially operate with a single lane in one direction (northbound), providing a new route for traffic travelling towards Fareham, Wickham and the surrounding local road network. This arrangement will allow the remaining works, including landscaping and footway completion, to be carried out safely.

For Dean Farm, access will be made available at Welborne Approach Roundabout for traffic travelling from the new westbound off-slip road, as well as for vehicles travelling from A32 Fareham and Wickham.
Please see the plan below, which shows the new westbound off-slip road and direction of travel.
