"With the extreme weather conditions, more traffic that is heavier and wider, our rural roads are not coping. If investment in roading maintenance doesn't keep pace with roading costs, which are forecast to increase significantly, we're looking at a major shortfall in roading maintenance budget over the next decade.
"Whilst the increase in maintenance and improvement costs appears to be reasonable, the Society of Local Government Managers (SOLGM) 'Forecasts of Price Level Change Adjustors 2013 Update' has roading costs increasing at around 3.5 per cent per annum until 2023.
"We have identified the economic value in investing in our 'Seven Roads of National Significance', now we need to do the same with our rural roads. Increasing our investment here will keep our input, output, and processing and export costs lower, keeping us competitive in the export markets.
"Whilst our industry grows, so should the investment in our infrastructure. Investment here is an investment in economic returns," concluded Milne.
