Inner City Bypass Upgrade project

Project overview

Transurban has reached in-principle agreement with the Brisbane City Council to deliver the $60 million Inner City Bypass (ICB) Upgrade project.

Under the agreement, Transurban Queensland will finance and project manage the delivery of the design and construction phases, and provide operations, routine maintenance and incident response services once the upgrade is completed.

The upgrade will include:

  • widening the ICB westbound from three to four lanes between the RNA tunnel and the Legacy Way portal
  • widening the ICB eastbound from three to four lanes between Legacy Way portal and Herston Road exit
  • construction of a new westbound ramp to the ICB from Bowen Bridge Road
  • provision of operations and incident response for the length of Legacy Way concession (2065)
  • provision of routine maintenance services on a 10 + 10 year contract (at option of Council)
  • Enhanced Intelligent Transport Systems


The ICB is adjacent to Transurban Queensland’s Legacy Way, Clem7, Go Between Bridge and AirportlinkM7 tolled roads, allowing Transurban Queensland to deliver a high standard of operations throughout the corridor to improve traffic flows.

The upgrade will ensure this critical inner-city road transport corridor remains flowing for years to come.

The project will deliver:

  • increased capacity for existing and future traffic demands
  • enhanced safety for all road users through improved traffic management and incident response clearance
  • improved connectivity to the wider road network
  • improved public transport options
  • The whole of network approach that Transurban Queensland brings will provide safer, more reliable journey for motorists with a 28% improvement in accident clearance times.

Timing and cost

The upgrade will be delivered at no cost to Brisbane rate-payers, with Transurban Queensland financing the design and construction of the project as well as providing operations, maintenance and incident response services once the upgrade is completed. Subject to the final agreement with Council, the project will be funded through adjustments to toll prices for vehicles using Clem7, Go Between Bridge and Legacy Way.

BMD Constructions has been selected to design and construct the ICB upgrade. Early works on the project have begun and are expected to be completed by mid-2018.
