Future discounts on major Sydney toll roads, as well as a reduction in the rate of price increases, were announced by NSW's government on Monday. "There's induced demand as governments are applying billions of dollars to toll relief, driving up the number of motorists on our network," Mr Minns said. The rate of toll increases on harbour crossings will decrease from 4 per cent to 3.25 per cent from July 1.
