The cost of Melbourne’s West Gate Tunnel is already blowing out, and commuters are going to be the ones copping it.

According to the Herald Sun, it’s now expected to cost around $45/week, with fares for commuters coming from Geelong and the west set to be at an eye-watering $5.64 during the morning peak and $5.64 on the way home.

The tunnel is expected to open in 2022 and the state Government signed off on the fares in June this year.
