River Road is classified as a Regional road which has a traffic volume of around 20,000 vehicles per day. The embankment in question is on the southern side of River Road and supports a section of roadway adjacent to Standish Street and opposite property no’s. 146 to 150 River Road. In this area River Road has three traffic lanes, with two lanes eastbound and one lane west bound.

Lane Cove Council noticed signs of instability in the embankment in the form of cracks and scouring. Council subsequently engaged Jeffery & Katauskas Pty Ltd to do a preliminary investigation to provide recommendations for its stabilisation.

On March 21, 2016, River Road Embankment Stabilisation using Soil Nails at River Road tender for Lane Cove Council has been awarded to Specialised Geo with a tender price of ​$846,700 (excl. GST).

Wollongong City Council are organising a Community walk to celebrate the reopening of Mt. Keira Road.  Illawara residents are being encouraged to participate in this event on November 8th, 2014.    Participants can enter either the 6.5-kilometre “School2Summit” cycle climb, kicking off from Edmund Rice College, or the 5-kilometre Summit Walk, starting from Mt Keira Demonstration School.  Return shuttle buses from the lookout will be free for walkers.

In November 2013, The Wollongong City Council have contracted Specialised Geo to undertake the road remediation geotechnical works at Mt Keira Road to reduce slope instability risk in the area and subsequently re-open the road to traffic with an acceptable level of risk. Specialised Geo have completed the job on both the upper cliff face and the lower embankments in July 2014.
