Motorists are being advised of road closures in the Thinford roundabout area over the next three weeks.
Resurfacing work is due to take place, which will inevitably mean some disruption for road users.
Part of the north section of the roundabout will be closed and a signed diversion via the A167 will be in place.
Between 7pm and 6am the A688 between Metal Bridge, to the east of Thinford, and Green Lane, to the west will be closed. Diversions will be signed in both directions and two-way traffic will continue to run on the A167 during this closure.
The closures will be in place from Monday, July 16.
The work is part of a wider improvement scheme in the area.
