SUNSHINE Coast council will hire a geotechnical engineering consultant to investigate a dangerous landslip on Duke Rd, Doonan (opposite the Panorama Dr turn).
Local residents became concerned after the verge on the side of road began collapsing leaving barely a metre between the road and the landslide.
One resident said he had noticed about a metre fall away in just a few days and slide down the badly eroded cliff.
He believes it can be attributed to heavy rain.
Last Thursday morning, a yellow council sign warned of the danger and four sections of yellow council fence cordoned off parts of the eroded verge.
By Friday a further fence had been erected and 40km speed sign put up.
In the meantime the council said work begins this week to temporarily widen the road on the southern side to allow the traffic to be moved over away from the slip face and still allow two-way traffic flows.
The centre line will also be moved over.
Council said they would rely on the consultant's report to propose a remediation design, but it was likely to take several months for the work to be completed as it appeared bore logs would be required.
The spokesperson said Council's Capital Works Services would maintain the necessary measures to ensure the road remains safe to all users in the interim.
