Specialist rockfall contractors will be undertaking work to scale the rock face of the Abbey Craig and remove loose material.
Alloa Road had previously been closed to westbound traffic after a rock fall left the Abbey Craig face unstable.

To allow for further essential safety repairs to take place, the road will now be fully closed at 7am on Monday and work is expected to continue on site for up to eight weeks.
Convenor of Stirling Council's Environment and Housing Committee, Councillor Jim Thomson, said: "In the interest of public safety, it is necessary to close this road while the contractors undertake the task of scaling back the fractured rock.
"We understand the closure is going to cause inconvenience for drivers, however this work is significant and much-needed to ensure local residents and commuters remain safe on the A907 and surrounding areas."
A diversion will be in place via the A91, A905 Kerse Road and the A9 Burghmuir Road and the A9 Causewayhead road.
