The ICB is a major motorway standard road in Brisbane. The 4.5km road bypasses the Brisbane central business district, connecting Brisbane’s Pacific Motorway and Go Between Bridge to Kingsford Smith Drive, Legacy Way Tunnel, Clem Jones Tunnel, AirportLink Tunnel and Lutwyche Road.
​
The ICB upgrade was an initiative of Brisbane City Council and was delivered by Transurban. The $60m upgrade increased capacity, improved travel times and safety for all road users, and improved connectivity to Brisbane’s wider road network.
​
This important project saw the ICB widened from three to four lanes in each direction between Legacy Way and the RNA tunnel, allowing for future growth. A new westbound ramp to the ICB, built as part of the project provides drivers with direct access to the Legacy Way tunnel, improving outbound afternoon traffic during peak travel times.
