Critics are taking aim at a traffic safety trial that has exceeded its budget by $300,000, Stuff reveals. A local board is spending $822,000 installing plywood boxes to block streets in the Auckland suburbs of Onehunga and Glen Innes. The project aims to redirect cars from narrow residential streets back onto main arterial roads, to create safer local streets. A petition opposing the trial in Onehunga has accumulated 1200 signatures, and an Auckland Transport survey of 1574 people found 75 per cent did not support the trial.
