Calls for the upgrading of the A90 from Ellon to Peterhead have intensified following a serious accident.
A police dog handler was left fighting for life when his van was in collision with a car at Auchiries, near Hatton, last Tuesday night.
Constable George Shearer, 46, is said to be in a stable condition in Aberdeen Royal Infirmary, where he is being treated for head injuries.
The 58-year-old driver of the Vauxhall Astra also sustained serious injuries in the accident, which occurred around 11.50pm and closed the road for several hours to allow investigations.
Police Scotland said that one of the two police dogs travelling with Constable Shearer, a nine-year-old black Labrador, Sam, had to be put down after developing complications following surgery.
Road policing inspector Jon Barron said: “I would be very keen to speak with anyone who may have seen either vehicle shortly beforehand, or anyone who witnessed the collision and who hasn’t yet been spoken to by police. Please contact us on 101.”
A long-running campaign has pressed for the upgrading of the single carriageway route.
Ellon and District Councillor Gillian Owen, who spearheads the Why Stop at Ellon dual carriageway initiative, has called for urgent action.
She said: “My thoughts are with the families at this difficult time.
“Too many accidents occur on this section of the A90.
“Currently we do not know what happened and we should not speculate, but as I have said before this road is poor an urgent action is needed.”
Mrs Owen added: “Time is off the essence and urgent action is needed to solve this recurring issue.
“The road surface along that section adjacent to Cruden Bay is poor, the white lines are poor and the edges of the road in some areas are hard to see.
“This stretch needs to be assessed immediately and any remedial work carried out soonest.
“Any measures carried out now could stop future accidents.”
