North motorists are facing more misery as work starts next week on two underpass projects that are part of the A9 Inverness-Perth dualling scheme.
Drivers will face disruption for 12 days from Monday as temporary traffic lights go up at Allt an Fhearna to the north of the Kincraig-Dalraddy stretch and at Dunachton Burn to the south.
Works on each 330 yard section of road will be completed sequentially, with the road reduced to one lane in both cases.
A 40mph speed limit under average speed camera control is already in place along the length of the Kincraig-Dalraddy project.
Transport Scotland has advised motorists to plan ahead for their journeys.
A spokeswoman said: “Transport Scotland apologises for any inconvenience caused by the works and thanks road users and local communities for their patience as work continues on this major project.”
Works are also underway on a 0.3mile stretch of the Inverness to Perth road at Badacreamh south of Daviot, with drivers limited to 10mph under convoy.
The two-week long roadworks involve the closure of a southbound lane of the dual carriageway stretch of the road.
Work will also get underway south of Slochd for another two weeks from Monday, November 9, with drivers again limited to 10mph under convoy for about half a mile.
Upgrades at both sites will be carried out between 7am and 7pm, with no work scheduled for weekends.
Traffic management will be removed outwith those hours but a 30mph limit will remain in place as traffic will be running on a temporary surface.
Plans to upgrade another stretch of the A9 that is due to be dualled will also go on show on Monday and Tuesday.
The 5.2mile stretch between Tomatin and Moy, south of Inverness, is the most northerly section of the £3billion dualling programme.
Exhibitions will be held at Strathdearn Village Hall in Tomatin between 4pm-8pm on Monday and 11am-4pm the following day.
They will give people the chance to see route and junction options for the project.
