The PTP Alliance has been created to deliver community-based and value-for-money public transport solutions that improve liveability and connectivity for South Australians – delivered safely and with minimal disruption to local communities.

Bringing together transport projects as part of a program of works under an Alliance ensures that all projects in the program have a consistent quality of delivery. When you walk past a PTP Alliance project, the safety outcomes, the way that the community is engaged and the commitment to minimising disruption is consistent irrespective of the complexity, the size or the location of the project.
