Drivers are facing overnight closures on the M80 for around four weeks due to repair works.
BEAR Scotland said works to repair subsidence on the slip road exiting the northbound M80 at Junction 9 at Stirling will commence on Monday.
The road was closed for safety in June as a result of “significant subsidence in the carriageway”.
Traffic has been using a temporary link road that was constructed to bypass the area where subsidence occurred since August.
That road will be closed during the repair work between 8pm and 6am on Monday to Friday nights, starting on Monday for four weeks.
Drivers will be diverted northwards on the M80 to turn at Junction 10, before returning southbound to exit via the M80 Junction 9 southbound off-slip.
BEAR said it will add approximately ten miles and 11 minutes to affected journeys.
Tommy Deans, BEAR Scotland’s south east network manager, said: “We now have a clear programme for the repair and reinstatement of this slip road.
“We’re grateful to road users for their patience and understanding while we completed site investigations and design work.
“It was important that this process was thorough, as we needed to understand the ground conditions that led to the subsidence and there was a possibility of unrecorded mine workings at this location.
“We’re now confident we have a designed a repair that is fit for purpose and look forward to getting the road reopened before Christmas.”
