A multi-modal flood-immune second river crossing in Ipswich Central will future-proof the inner-city road network against population growth, increasing flood risk and unsafe driving conditions due to increasing congestion. A second river crossing will support connectivity, inner-city revitalisation, and economic development by providing an alternative route for through traffic. A second river crossing is integral to enabling Ipswich Central to fulfil its roles as a Principal Regional Activity Centre.

About the Ipswich Central Second River Crossing project

Why is this project important?

Benefits to Ipswich:

  • Unlocks bottleneck and improves road safety
  • Provides safe, flood-immune connectivity across the city
  • Facilitates public and active transport connectivity
  • Enables Ipswich Central to fulfil its role as economic centre
  • Improves cross-river connectivity and permeability.

Benefits to South East Queensland:

  • Disperse congestion
  • Strengthen regional road network efficiency and resilience
  • Improve road safety
  • Provide a flood-immune crossing
  • Support economic productivity
  • Supports national highway diversion routes
  • Leverage $300 million investment in Ipswich Central.

If we do nothing:

  • Excessive congestion will cost the economy $70 million p.a. in 2036
  • Higher than average avoidable crash rates will persist, costing $18 million p.a. in 2036
  • Network failure during incidents and flooding
  • Local businesses will continue to suffer from congestion and amenity impacts.

Success to date

Council delivered the Strategic Assessment (Stage 1: Business Case) in 2017 and Preliminary Business Case (Stage 2: Business Case) for this project in 2020, which was revised in 2023. These investigations identified a second river crossing to be the preferred solution to combating congestion in Ipswich Central and to further support the redevelopment of the Ipswich city centre to be a vibrant and prosperous principal regional activity centre. Earlier feasibility studies were delivered with the support of the Queensland Government.

The Stage 1 submission has been assessed by Infrastructure Australia and has been included on the Infrastructure Priority List as an early stage proposal.
