A semi-trailer roll-over has highlighted the poor condition of Maria River Rd.
The vehicle was hauling 22, one tonne bags of fertiliser for a Kempsey trucking company. It rolled over on Wednesday about 10 kilometres along the unsealed road from the intersection with Shoreline Dr.
The driver of the vehicle was shaken but uninjured.
Emergency service vehicles were unable to reach the vehicle for more than 30 minutes after the call out coincided with a breakdown of the Settlement Point Ferry.
Emergency services had to travel to the scene via the Hibbard Ferry.
Fire and Rescue NSW's Port Macquarie station officer Geoff Peacock said the call out was received about 1pm.
"Luckily the driver was not trapped or injured in the incident," he said.
"The truck was hauling big bags of fertiliser and has rolled over negotiating a corner of the road on the north side of Mundays Ln.
"Traffic will still be able to move along Maria River Rd until a crane is onsite to remove the fertiliser bags and right the semi trailer.
"But we will be here for several hours."
Some 20 litres of hydraulic oil, five litres of engine oil and 'only a few litres of diesel' were spilled at the crash site.
Police and RMS investigations into the crash are continuing.
Paramedics, the Hazmat vehicle and RFS units from North Shore, Sancrox and Lake Innes brigades also attended.
It could also shed more light on the need for extended ferry operating hours.
