Sydney has an extensive network of toll roads, and it's a nightmare. The state government has outsourced the initial infrastructure development to a private company (Transurban), who pay off their development costs through collecting the toll. It costs taxpayers a fortune. Sydney's road network is so poorly designed that it's difficult to get anywhere without crossing a toll road if you actually value your time. People allege that the state government is deliberately designing bottlenecks into the road network to funnel traffic into toll roads (e.g. westbound traffic on Parramatta Road) and it's difficult to disagree with this assessment. I live in the city and most of my driving is for leisure, yet somehow I still paid $850 in tolls over the last 12 months. Just in case anyone is wondering, there's no 'toll plaza'. Our toll roads have an automated collection system which operates via ALPR.
