The ICB is considered as one of Brisbane’s most important routes and is vital to driving the city’s economic growth. It is a major link in the road network because of its connections to Lutwyche Road, Airport Link Tunnel, Clem Jones Tunnel, Legacy Way tunnel, and Kingsford Smith Drive.
Carrying more than 105,000 vehicles per weekday at 90% capacity, the ICB is expected to exceed its capacity by 2021; hence the need for an upgrade.

The project is aimed at providing capacity for future growth and improving travel time along the bypass. The project was to also improve public transport facilities and connectivity to the road network.
