Transport noise corridors
A designated transport noise corridor can be a state-controlled road, railway or major local government road that's been designated and gazetted by the state or a local government under the Building Act 1975.
As Queensland's population grows, more residential development will be located close to major transport routes.
To minimise the impacts of transport noise on dwelling occupants, the Queensland Government has streamlined the building application approval process for residential buildings constructed in designated transport noise corridors.
Find out about the code for building in transport noise corridors.
Mandatory and voluntary areas
The state-controlled road network is separated into 2 areas: mandatory area and voluntary area.
The voluntary area reflects the relatively lower risk to noise exposure that these roads pose to occupants.
If a property and building is wholly or partly in the:
- voluntary area: the building owner can choose to include the relevant noise category measures under MP 4.4
- mandatory area: the building owner must comply with the relevant noise category measures under MP 4.4.
The transport noise corridor mapping tool provides details of these areas in the results for a property search.
The Queensland railway lines designated as transport noise corridors are:
- all the South East Queensland network (excluding the Interstate line and the Richlands to Springfield line)
- the North Coast Line System (Nambour to Cairns)
- the Western System (Rosewood to Oakey)
- the Mount Isa System (Stuart to Mount Isa).
The transport noise corridor mapping tool provides details of these railway corridors in the results for a property search. They are mandatory areas for compliance purposes.
The State Development Assessment Provisions no longer contain provisions about internal noise for residential buildings in these rail corridors. We don't attach conditions to these development applications.
A building development application for a property affected by a railway corridor must comply with MP 4.4.
