Memorial Drive embankment stabilisation and new footpath
We reestablished a 115m section of embankment along Memorial Drive, The Hill, following a land slip during a period of significant rainfall.
Council voted to accept a tender for the embankment stabilisation works on 27 February, with the project commencement from late May through to November 2024 (pending weather).
The project was delivered by City of Newcastle (CN) with around $3 million funding from the Federal Government's Roads to Recovery Program.

What work was needed?
We carried out extensive geotechnical investigations to determine the work required for this complex project, which takes into consideration the constraints presented by this site.
A new retaining wall was constructed as part of the stabilisation works, with a series of steel-reinforced concrete piles poured vertically through the underlying rock. Upgrades at the base of the existing stormwater channel will also help improve the flow of water during periods of heavy rain.
We also constructed a new street-level footpath on top of the renewed embankment to replace the temporary access, while kerb and guttering and road resurfacing work was also be completed.

Project update:
June 2024 - The first stage of major work started with the construction of a new concrete piled retaining wall to stabilise the road embankment retaining wall.
August 2024 - Concrete piles have been installed for the retaining wall. We are working on pile capping, embankment stabilisation earthworks and stormwater upgrades (to extend down the gully).
September 2024 - The concrete pile capping beam construction was completed. Works commenced on the utility relocations and pavement preparation on Memorial Drive. The stormwater upgrades also continue in the gully with increased plant movements on Nesca Parade.
October 2024 - Utility relocations, kerb and gutter, and guard rail installation are completed. Stormwater upgrades in the gully continue.
November 2024 - Footpath, guardrail, and road pavement works are completed on Memorial Drive. Traffic controls have been removed and the footpath now open to the public. Stormwater upgrades and earthworks in the gully are completed. We will be working with our local Landcare Group for embankment revegetation restoration along with some other minor works prior to the Christmas shutdown.
We would like to thank the community for their patience and understanding throughout the successful delivery of this project.
