A road which was dubbed one of Scotland's deadliest routes has been closed twice in one day following separate crashes.
More than 80 people have been killed on the A9 since 2002
The A9 was blocked northbound near Blackford following an accident involving two vehicles.
Three people were trapped and taken to hospital, with one flown to Ninewells in Dundee by air ambulance.
The A9 north of Perth was earlier closed at Bankfoot after a pedestrian was struck by a heavy goods vehicle.
The 30-year-old, from Motherwell, was pronounced dead at the scene.
The accident happened at about 0445 BST, about half a mile south of the junction with the B867.
Tayside Police said the victim's green Peugeot 406 was parked in a lay-by nearby.
They have appealed for information from anyone who saw it, or saw anyone walking along the road before the accident.
The lorry driver was not injured in the collision, which closed the road in both directions, leading to about five miles of traffic queues.
The second crash happened at about 1040 BST on the A9 between Stirling and Perth.
Tayside Police said a blue Renault Kangoo estate car which was crossing the carriageway into Blackford collided with a blue BMW M5 car.
The passenger of the Renault, a 42-year-old man, was airlifted to Ninewells Hospital in Dundee with "very serious injuries".
He was being treated in the High Dependency Unit, along with the 74-year-old driver.
The driver of the BMW, a 67-year-old man from Braco, sustained minor injuries, and was taken to Perth Royal Infirmary for a check-up.
Officers have appealed for witnesses to the crash, in particular an off-duty staff nurse and an off-duty paramedic who stopped to help at the scene.
An off-duty fire-fighter, who also gave assistance, has already been traced.
The A9 has previously been branded one of the most the deadly roads in Scotland.
More than 80 fatal collisions have occurred there since 2002.
