Project information
Overview
The improvements for M27 junction 10 include the provision of:
- a new underpass underneath the M27 west of the existing junction
- two new slip roads
- a replacement for the existing west-bound exit slip road to create a junction that works more effectively for everyone using it
Hampshire County Council is leading with the M27 junction 10 improvement scheme, which supports the new Welborne Garden Village.
Full information on this scheme and latest updates can be found on the Hampshire County Council website.
Benefits
By working closely with Hampshire County Council, we will see an improved junction access, which will accommodate additional traffic from the new homes at Welborne Garden Village.
Our close working will ensure traffic disruption is minimised as much as possible during construction, while seeing an overall benefit to all our customers once the scheme is fully open.
