The cash comes on top of more than £137 million which has been spent on the road - which links Perth with Inverness - since 2007.
That money has funded work to improve junctions and overtaking opportunities, as well as covering ongoing maintenance, with the bulk of the cash coming from the Scottish Government agency Transport Scotland.
Members of the A9 Safety Group - which includes Transport Scotland as well the police, the Road Haulage Association and others - informed MSPs about the work being done on the busy road.
Road operators BEAR Scotland will be carrying out a programme of works on the route, ranging from tree-cutting to major resurfacing work.
The firm recently began replacing the lighting at the junction at the A824 Auchterarder junction with new lamps which are designed to reduce the severity of accidents and also provide better illumination.
Police Scotland are targeting bad drivers in a bid to reduce speeding and dangerous motoring on the road, and average speed cameras are to be installed on the route next year.
The Scottish Government has already pledged to upgrade the A9 to dual carriageway by 2025.
Stewart Leggett, chair of the A9 Safety Group, said: "The safety issues on the A9 are complex and a variety of solutions are being used to help cut the number of fatal and serious accidents.
"As a result, the A9 Safety Group's actions to address these problems are wide-ranging, concentrating engineering, education and enforcement.
"We know that all of these areas need to be addressed to save lives and we will be making progress across the board in the coming months.
"Significant investment continues to be made in maintenance as this is where some of the simplest solutions, such as improved lining, can have clear benefits.
"This will be backed up by public education campaigns on dangerous overtaking as well as continued enforcement from Police Scotland."
He said average speed cameras had been shown to be "consistently effective in reducing accidents, particularly those resulting in death and serious injury".
Mr Leggat added: "The A9 Safety Group firmly believes that its co-ordinated programme of improvements will cut the number of accidents on the route in advance of and throughout the period of dualling."
