Long delays have been reported during the first morning rush hour of roadworks on the A90 Aberdeen road at Stonehaven.
Nearly a mile of resurfacing works began on Friday as part of an £800,000 project by Amey.
Lanes will be closed and a contraflow system will be in operation until Sunday, March 5.
This week, long delays were reported in Stonehaven as A92 Montrose traffic from the south was diverted through the town.
Motorists have reported taking up to 90 minutes to get to Aberdeen city centre, about an hour longer than the normal drive.
Congestion was reported at the Dunnottar turnoff on the A92 south of Stonehaven, through the town itself and at the A90 AWPR junction where northbound traffic is able to rejoin the road.
What works are being done on A90 at Stonehaven?
The first wave of roadworks will span the northbound carriageway between the A92 Dunnottar road sliproad and the railway bridge.
Traffic from the A92 travelling north to Aberdeen will be diverted through Stonehaven during the closures.
The second section will stretch for about half a mile northbound to just south of the sliproad for the Spurryhillock Industrial Estate and Kirtown Garden Centre.
The work began on Friday, February 24 to allow the contraflow to be set up with all resurfacing due to be completed by 6.30am on Sunday, March 5.
The A90 is one of the busiest roads in the north-east with up to 15,000 using the section near Stonehaven every day.
