This has led to concerns regarding safety, as the road is frequented by both pedestrians and cyclists. After the death of a cyclist in 2007, calls for the repair and resurfacing of the road intensified, with two petitions being tabled in parliament. The accident also led to a safety audit being conducted by TransportSA, and although the results were not released to the public at the time, it called for an investigation of the entire length of the road. As of mid-2008, there has been no clear plan released for the future of the road, with the road missing out on funding in the 2008 state budget.
