Perth and Kinross Countryside Trust (PKCT) has raised a formal planning application to create a new footpath and cycleway between Bridge of Earn and Aberargie.
The Pullar House-based charity wants to form the proposed active travel route along one side of the A912 in order to provide pedestrians and cyclists a safe route to travel back and forth between the two settlements and beyond.
Local politicians have backed the project but critics have previously raised concerns a planned reduction in the width of the road to accommodate the new route could put drivers at greater risk of colliding with oncoming traffic.
