DRIVERS are being warned to expect disruption when parts of the M3 and Black Dam interchange are closed over two weekends for roadworks next month.

National Highways says it is planning carriageway repair work at junction 6 of the M3, which links the motorway to the A339 and Black Dam roundabout, in Basingstoke. To do this safely, it will close several key links at the Black Dam interchange in two weekend phases from late April.

The roundabout link between the coastbound M3 and the southbound M3 spur to Black Dam will be shut, along with the northbound spur from the junction 6 roundabout back to Black Dam. Slip roads leading from both the London‑bound and coastbound carriageways of the M3 at junction 6 will also be affected.

Each weekend closure will run from 9pm on Friday until 6am on Monday, with work expected to take around a month in total. The order comes into force on April 22 and can last for up to 18 months, although the restrictions will be lifted once the scheme is complete.

Drivers will be diverted via the M3, the A287, the A30 and Winchester Road, with signed diversion routes in place. National Highways says the measures are in the interests of safety while contractors carry out the repairs and associated works.
