Construction of a temporary link road at M80 Junction 9 is expected to be complete by early next week, providing access from the M80 northbound to Pirnhall Roundabout and Stirling Services while the main slip road remains closed due to subsidence.
The M80 Junction 9 northbound off-slip has been closed for safety reasons since 28 June due to significant subsidence in the carriageway. Since then, Transport Scotland’s operating company BEAR Scotland and the Coal Authority have engaged specialist contractors to carry out ground investigations. The Coal Authority has also been considering the impact historical mine workings may have had on this section of the motorway.
On 30 July BEAR Scotland announced its intention to construct a temporary link road bypassing the area where subsidence occurred. These works are now nearing completion, with the new link road expected to open to traffic by early next week.
To allow the temporary link road to be surfaced and road markings applied, overnight closures of the M80 northbound carriageway will be required between 20:30 and 06:00 on the nights of Thursday 8 August, Friday 9 August and Monday 12 August.
A diversion route will be signposted on these nights from M80 Junction 8 to M9 Junction 9 via the M876 and the M9, adding an estimated ten miles and eleven minutes to affected journeys.
Once the temporary link road opens, reduced speed limits will be enforced by Police Scotland average speed cameras over a three-kilometre stretch of the M80 northbound.
Occasional lane closures will also be required to allow the longer-term repair of the main slip road to progress.
Tommy Deans, BEAR Scotland’s South East Network Manager, said: “Construction of the temporary link road has progressed well and we expect it to open to traffic by early next week, restoring access to Pirnhall Roundabout and Stirling Services from the M80 northbound.
“Motorists should be aware that Police Scotland average speed cameras will be enforcing reduced speed limits while the temporary link road is in operation. This is necessary for safety due to tighter than normal bends in the road layout.
“We are working at pace to complete ground investigations, design a long-term repair of the main slip road and certify and construct that design. We’ll continue to provide regular updates.
“We’re grateful to road users and local communities for their continuing patience in the meantime.”
