Don't use toll roads. You already pay your taxes, so why should you pay more?
Leave home a little earlier and use the non-toll roads. It takes longer, but if you depart earlier, you will get to your destination at the same time.
For example, I live on the south (city) side of Sydney Harbour but work on the north side. The easiest way for me to get to and from work each day is via the Sydney Harbour Bridge. However, there is a toll on the SHB for all traffic travelling southward (not northward). So when I travel northward to work in the morning, I take the SHB (no toll) and coming back home, southward, in the evening, I travel by the non-toll Gladesville Bridge. It's a slightly longer journey, but I avoid the toll.
I know what you're thinking - I pay just as much on extra petrol for the longer journey as I would on the bridge toll. Well, no, I don't. Though it is slightly longer to drive via the Gladesville Bridge, at least the traffic is moving smoothly all the way, with no stop-start driving, as opposed to the SHB, which is constant stop-start, high petrol consuming driving all the way. And I drive a very fuel-efficient, small car.
By doing this, I save the $3 daily bridge toll! Not a lot, you say? Well, that $3 adds up to a saving of $15 a week and $780 a year!
For the 14 years I've been living at my present address, that's
$10,920!!!
