Centenary Motorway and Logan Motorway interchange upgrade

We are in the business case phase for the Centenary Motorway and Logan Motorway interchange upgrade.

We are planning to duplicate the northbound carriageway from 1 to 2 lanes. This will help manage congestion, particularly during morning peak periods.


  • Improves safety
  • Increases capacity
  • Improves network efficiency
  • Reduces peak hour congestion
  • Reduces interchange queuing
  • Reduces travel time
  • Contributes to economy

Key features

  • Upgrading the existing interchange for northbound road users
  • Upgrading the carriageway from 1 lane to 2 lanes
  • About 1.5km of localised pavement widening, new guardrail and concrete barriers, relocation of light poles, moving the median and gantry removal


As part of the $400 million road stimulus package, the Queensland Government committed $15 million for the upgrade to support Queensland’s Economic Recovery Strategy: Building Queensland by driving investment in the infrastructure that supports our recovery, resilience and future prosperity.
