From Taxes to Tolls. Stephen Selwood
Transport pricing — ensuring the price of transport infrastructure promotes efficient use of the network. Stephen will draw on lessons learned in the UK, Sweden and the US and look at how road pricing might be introduced in New Zealand and its potential to transform network efficiency. Stephen is a professional company director and an […]
How do you prioritise work on bridges? Kyle Blyth, WSP
New Zealand has an aging infrastructure network with many iconic and heavily used bridges. It is commonly assumed by Asset Owners that, at the end of their original design life, bridges are in immediate need of replacement.
