The NSW Government will introduce a congestion toll on the Sydney Harbour Bridge and Harbour Tunnel in an Australian first.

Different charges will apply at different times of the day, with the toll rising to $4 during peak periods. The changes will take effect "by February".

In a mini-budget aimed clearly by a Premier without a driver's licence at the problem of urban congestion, the Government has also announced a major increase in CBD parking levies in a bid to discourage people from driving into the city.
