Heavy-commercial vehicles will see increased toll prices along three Brisbane roads from mid-2018 to cover the cost of the $60 million Inner City Bypass upgrade.

The increases will be for trips taken between 5am and 8pm only, with the intention to take trucks off the tollways during peak periods, thereby reducing congestion.

Brisbane City Council infrastructure chairman Amanda Cooper said the increased toll charges would fund the upgrade, rather than the project being solely funded by Brisbane taxpayers.
