“An extraordinary achievement" as M27 reopens 24 hours ahead of schedule

The M27 has reopened this morning after major works as part of the upgrade of junction 10 were completed.

Hampshire County Council has confirmed that the M27 reopened at 4am this morning (January 3) between junctions 9 and 11 after a ten-day closure - 24 hours ahead of schedule.

It said this was “an extraordinary achievement after one of the most complex engineering operations Hampshire has ever delivered”.

In a statement the council said: “Over the previous ten days, around 130 people worked day and night through the Christmas period, contributing a combined 10,000 hours to install a brand‑new underpass at Junction 10 using an innovative “box slide” technique.

“A 60‑metre concrete structure, weighing 8,500 tonnes was slid 65 metres into place with millimetre precision, avoiding months of lane closures and disruption.

“The team worked continuously, day and night, from Christmas Eve until 3 January to complete this major operation safely and efficiently.

“A big thank you to everyone for your patience while this essential construction work took place.”

The installation of the new underpass paves the way for Junction 10 to be made into an ‘all ways’ junction - meaning you can enter and exit in both directions. Currently this is only possible in one direction.

The works have been prompted by the construction of the new 6,000-home town at Welborne Garden Village where construction is new underway and the first homes sold.
