The Ipswich to Springfield Central Public Transport Corridor (I2S Corridor) is a designated public transport corridor traversing residential expansion areas of Ripley and Redbank Plains.

By providing a strategic link to Brisbane and an efficient alternative to private vehicles for over 200,000 people, it will promote economic prosperity, productivity, and social inclusion by providing access to jobs, education, services and recreation.

This project is a critical element of addressing public transport underinvestment throughout Ipswich. Connectivity between Ipswich and Springfield is inadequate and not meeting community expectations, and growing areas with family-based demographics including Redbank Plains have limited access to public transport.

Progression of this project is imperative to catering to growth and will improve mobility for the 2032 Olympic games.

$10 million is required to progress this project to shovel-ready status by selecting and developing preferred options for a mass transit solution in the I2S Corridor.

In the short term, $1 million of federal funding is required to supplement committed Queensland Government and Ipswich City Council funding to complete the Stage 2: Options Analysis.

Council is also asking the Queensland Government to bring forward its contribution to the 2022-23 budget year.

About the I2S Corridor Project

Why is this project important?

Benefits to Ipswich:

  • New local economic hubs
  • Transit-oriented development and housing
  • Connectivity to essential services such as health and education

Advocacy success to date

Council delivered the Strategic Assessment (Stage 1 Business Case) for this project in 2020. It provided a preliminary shortlist of possible mass transit solutions for further investigation in future business case phases:

  • heavy rail
  • light rail
  • trackless trams
  • bus rapid transit.

In 2020, the Strategic Assessment was provided to the Department of Transport and Main Roads which is reviewing it for use as its Strategic Assessment of Service Requirement (SASR).

As a result of the Strategic Assessment, this project is now included as an Early-Stage Proposal on Infrastructure Australia’s Infrastructure Priority List.

Council secured an election commitment from the Queensland Government in 2020 for $1 million towards the Options Analysis (Stage 2 Business Case) for this project.

Council has also committed $500,000 towards the Options Analysis.
