The two authorities are backing the district council's application for subsidies.
Pipiwai Titoki advocacy group spokeswoman Alex Wright said there were other road safety issues caused by up to 80 heavy-haulage vehicles a day using Wright and McCardle Rds. Twice a day the local school bus travelled the worst affected roads, often in white-out conditions, she said.
"The driver has one hand on the steering wheel and the other hand on the RT (radio telephone) so she can find out where the next logging truck is on the road - she can't see for the dust."
WDC is also calling for the Mangakahia to Otaika route to be designated a state highway. Mr Martin said 49 per cent of the forestry traffic using local roads came from the Far North and Kaipara districts.
"It is not equitable that these additional costs are being met by Whangarei ratepayers."
Mr Martin called for all stakeholders to "put their shoulders to the wheel" to get the local situation remedied. WDC sought as many supporting submissions as possible, he said. "It is critical we all work together."
Whangarei MP Shane Reti (National Party), Winston Peters (NZ First) and Maori Development Minister Te Ururoa Flavell (Maori Party) have all pledged to lobby the Northland roading issue in Parliament.
Whangarei District Council is asking NZTA for:
? The Regional Development Fund programme to fully fund sealing Wright and McCardle Rds, estimated $4.5 million.
? A fall-back option, the normal subsidy of 53 per cent to seal Wright and McCardle Rds.
? If both the above are unsuccessful, a 53 per cent subsidy to seal strips in front of houses.
