3.2.1.2      TMR’s Fauna Sensitive Road Design Manual
The conservation and protection of native fauna is important to TMR. Road corridors are maintained where
possible to support unique flora and fauna species. As part of the planning stage of projects, TMR completes
environmental assessments to understand the potential risks on fauna corridors, fauna habitat and the
potential for road kills, to inform the project design where possible. As part of the design process, TMR’s
Fauna Sensitive Road Design Manual is used to design, construct and maintain roads that better
accommodate the needs of fauna, by reducing habitat or population fragmentation and the impact of road
traffic.
The Fauna Sensitive Road Design Manual has been divided into two parts:
   Part 1 (https://www.tmr.qld.gov.au/business-industry/Technical-standards-publications/Fauna-
    sensitive-road-design-volume-1) provides information on past and existing practices to assist
    practitioners to design, construct and maintain roads that better accommodate the needs of fauna.
   Part 2 (https://www.tmr.qld.gov.au/business-industry/Technical-standards-publications/Fauna-
    Sensitive-Road-Design-Volume-2) provides information on preferred practices to assist practitioners to
    design, construct and maintain roads that better accommodate the needs of fauna.
Guidelines outlined in TMR’s Fauna Sensitive Road Design Manual have been incorporated into the
proposed action’s design, where relevant to reduce impacts to the identified MNES (refer Section 1.3).


3.2.1.3      TMR’s Road Drainage Manual
TMR’s Road Drainage Manual (https://www.tmr.qld.gov.au/-/media/busind/techstdpubs/Hydraulics-
and-drainage/Road-drainage-manual/RoaddrainagemanualComplete.pdf?la=en) provides information
related to the planning, design, construction, maintenance and operation of road drainage infrastructure. It
provides the technical reference required for all aspects of hydraulic, road drainage, erosion, environmental
and sediment control throughout Queensland.
TMR has generally agreed to adopt the guidance published in Austroads Guides to Road Design series
(https://austroads.com.au/safety-and-design/road-design/guide-to-road-design) as part of national
harmonisation. While the Road Drainage Manual remains the primary document, it references and adopts
criteria and methodology as published in the Austroads Guide to Road Design.
Guidelines outlined in TMR’s Road Drainage Manual have been incorporated into the proposed action’s
design to reduce impacts to the identified MNES, particularly in relation to any potential indirect impacts to
aquatic species such as the Mary River cod and Australian lungfish. The bridge will drain to the southern
embankment, where water will be carried away in a swale drain.


3.2.1.4      TMR’s Specifications
All site preparation, construction phase and dismantling of the existing bridge will be carried out pursuant to
the TMRs engineering standards and Technical Specifications. Environmental aspects will be managed
under site specific and relevant aspects of the MRTS 51 Environmental Management and MRTS 52 Erosion
and Sediment Control. Rehabilitation and landscaping works will be managed by MRTS16 Landscape and
Revegetation Works.
