M27 junction 10 closures: Mammoth 30-mile diversion route in place for overnight closures

The A32 northbound and the westbound exit slip road will be closed this evening (Tuesday, April 29) and tomorrow (Wednesday, April 30) from 9pm to 6am on both days, with south and eastbound closures on Thursday and Friday nights.

Official National Highways diversion routes of around 30 miles will be in place during these closures travelling via Titchfield, Swanwick, Botley and Wickham.

It comes as part continues in the area to upgrade the stretch of road to provide the infrastructure to facilitate the 6,000 home development at Welborne Garden Village, including transforming it so that you can enter and exit in both directions from and to the M27.

The scheme, which is costing in excess of £100m to complete, will see the construction of a new motorway underpass, three new slip roads, and a new dual carriageway to link the slip roads to the existing road network.

The four overnight closures for ‘essential’ BT cabling work are:

• The A32 northbound and the westbound exit slip road will be closed heading towards A32 Wickham between Tuesday, April 29 and Wednesday, April 30, from 9pm to 6am on both days.
• The A32 southbound and the eastbound entry slip road will be closed heading towards Fareham/ Portsmouth on Thursday, May 1 and Friday, May 2 between 9pm and 6am.

Hampshire County Council is overseeing the scheme and have been providing regular updates surrounding the progress being made at the junction.

The most recent update has said that the work is ‘progressing well’ and engineers have spent the last few months constructing a large ‘complex’ ‘guide slab’ alongside the motorway. This slab, which involves 1,000m3 cubic meters of concrete, will be used to slide a huge underpass into position later this year.

The project is expected to continue until summer 2026 and, as well as multiple road closures, a 50mph speed limit on this section of the M27 will be in place for approximately 12 months.
