A bill to extend tolls on CityLink for 10 more years will be introduced to parliament this week to pay for a new Transurban-operated toll road in Melbourne’s west.

Motorists will pay tolls on CityLink until at least 2045, to help pay for the $6.7 billion West Gate Tunnel, if the bill is passed.

The Andrews government struggled to get its extension to the CityLink concession deed through the last parliament, due to combined opposition from the Coalition and the Greens.

Those parties no longer have the balance of power in the upper house, although the legislation will still require support from at least crossbenchers to pass.

Premier Daniel Andrews said certain historical clauses in the current CityLink deed, which compensate Transurban if the state builds a project that diverts traffic from its toll roads, would also be scrapped.
