Overnight lane closures on the M27 will start on Monday as part of improvement works to Junction 10.

The closures are to support the Welborne Garden Village development near Fareham and will begin at 9pm.

The lane closures on the M27 will be between Junctions 9 and 10, and Junctions 9 and 11, depending on the night.

Hampshire County Council has said the closures are necessary to reduce the number of lanes on the motorway from four to three for the safety of both motorway users and construction staff working on the embankments.

This reduction will be in place for around 12 months, with a 50mph speed limit also enforced while the project continues.

The improvements to Junction 10 are set to support the development of Welborne Garden Village, a new community of up to 6,000 homes just outside Fareham, as well as to provide easier access to the M27.
