The 14 km corridor between Browns Plains and the South East Busway is a major transport corridor for public transport, freight and private vehicle users.

Growing population and traffic demand will exacerbate capacity, reliability and safety issues currently impacting the corridor. This is partly due to the lack of bus priority infrastructure. There are only 3.3 km of inbound T3 lanes available for use in the northern section of the corridor and no bus priority infrastructure in the southern section.

As a high frequency bus corridor, there are 18 buses per hour in the southern section and up to 57 buses per hour in the northern section during peak periods. Apart from the grade-separated busways in metropolitan Brisbane, the northern section is the busiest bus corridor in Brisbane.

The impacts of congestion, safety and passenger delay in the corridor is estimated at $64 million a year (2019) and is set to rise to $96.4 million a year by 2031.

This corridor connects people living south-west of Brisbane to Griffith University, the University of Queensland, major shopping centres and hospitals. It also provides access to the Brisbane CBD via the South East Busway.
