Department of Transport Regional Director (Barwon South West) Vanessa Schernickau said geotechnical engineering experts have been busy assessing the site and formulating plans for its repair since a major landslip closed the road in early January.
“Our first priority was to clear the site and prevent any further deterioration,” Ms Schernickau said.
“Now that those works are complete, we’re looking forward to getting on with repairing and stabilising the embankment to safeguard against any more landslips.”
From Monday, crews will be on-site to get the repair works underway, with works expected to take around three months to complete.
“We’re using a range of techniques to ensure that this site is stronger, safer and more secure,” Ms Schernickau said.
The initial focus of the works will be to construct a 42.5-metre-long and three-metre-high retaining wall around three quarters of the way up the embankment, before specialist contractors move in to complete a process called soil nailing.
This involves long metal rods being drilled into the embankment to reinforce the slope, before being covered with tensile mesh to anchor it into place.
Due to the heavy materials and equipment required, along with the specialist nature of the work, Deviation Road will remain closed to traffic while they are being carried out.
“While we understand that the ongoing closure of Deviation Road may be frustrating for some drivers, it’s important that we get these works completed as soon as possible and ensure the road is safe before we re-open it to traffic,” Ms Schernickau said.
While Deviation Road remains closed, detours are in place via Minerva Road, Autumn Street, McCurdy Road and Hyland Street and drivers are encouraged to allow for additional travel times of up to 10 minutes.
To cater to the additional traffic travelling along the detour route, traffic controllers will be in place during peak travel times, while RRV has also installed a temporary pedestrian refuge and speed detectors.
“We thank everyone for their ongoing patience while we complete these vital works and make Deviation Road safe for everyone,” Ms Schernickau said.
