Onkaparinga is making the Witton Bluff Boardwalk a path to the future, made with similar materials to surfboards to stop locals burning their feet and to prevent rust.
The boardwalk, made of a fibreglass composite, is currently being laid and is due to be complete by the end of 2024, with most of the framing on the southern limestone shelf now completed.
Work on the northern limestone shelf is continuing with footings being installed, with handrails and balustrades to follow. Each post is custom-made to fit the specific dimensions and angles measured on-site.
The seawall repairs are set to be completed by mid-2025, as for the pathways, work will commence after the completion of the sea wall. This will include raising the level of the path, the installation of lighting and fencing and installing an asphalt seal.
Director Operations at the City of Onkaparinga, Kirk Richardson,says “the trail will provide access for people of all abilities, encouraging the community to stay healthy and active in stunning surrounds, and boosting the local economy through increased visitation”.
The project got the green light in January following hefty discussions around the project. With a budget of $6.7 million, the Witton Bluff Base Trail is jointly funded by the State Government as part of its Coast Park project, and the City of Onkaparinga as part of its approved Coast Park Plan.
The Coast Park Plan identifies and prioritises segments along the City’s coast yet to be completed and the Witton Bluff Base Trail is the remaining link for a continuous coastal pathway from O’Sullivan’s Beach to Moana.
This transformative project aims to provide improved access to quality public open space while showcasing the scenery, geology, heritage, and natural beauty of the area.
During the construction period, the community can anticipate some disruptions, including construction-related traffic and noise, restricted access in certain areas for public safety, and the establishment of a site office in Port Noarlunga.
Access restrictions will be in place, and temporary disruptions may occur at the site entrances with controlled access for larger vehicles.
The Witton Bluff Base Trail project has a high community value and priority, offering economic benefits through construction and additional visitor spend, as well as environmental and cultural heritage protection. It also presents an opportunity to interpret Kaurna heritage through artwork, signage, and ongoing tourism potential.
With a rich history dating back to the 1970s and 1980s with the original section of path built to facilitate construction of the sea walls, it’s been in the community for some time.
