For the latest Structures Location Map refer to Road Information Mapping System.
The Structures Location Map Books listed below are intended for use by Main Roads' staff and its contractors or consultants.
These books were created with a geographic information system mapping application to input the structures locations onto special mapping data obtained from other Government agencies. For this reason, the quality and size of these files is very large and not recommended for viewing or downloading if you are using a dial-up Internet service.
Definitions for different structures are provided below to ensure the use of the appropriate inventory form and inspection form as well as ensuring the allocation of responsibilities for managing the asset is clear.
The applicable inventory form is required for each new or refurbished structure.
The General Bridge Inventory Information Form shall be used for gantries. A combination of the details contained in the general bridge inventory form and culvert inventory form shall be used for precast box unit bridges until a new form is developed for this specific superstructure type.
The Culvert Inventory Form shall only be used when a bridge has been replaced with a culvert (as per the culvert definition above).
Please contact the Bridge Condition Manager on 9323 4431 if you have any questions in relation to the use of any of these forms.
Utility Providers considering attaching services to an existing or new traffic bridge, traffic structure or other road service structure must contact the Asset Manager Structures in their region in the first instance. Below is the approval procedure for attachment of services to structures. Prior to commencement of any installation, a Utility Provider Service Management Agreement is required detailing maintenance, future removal or relocation, responsibility of costs and indemnity. An example of the wording required is attached below.
Reference must also be made to Our Roads/Conducting Works on Roads/Codes, Policies & Guidelines
An aluminium alloy plate is to be attached to each timber bridge at abutment 1 LHS and filled in after every termite inspection/treatment.
A bridge number tag is to be added to each bridge crossing sign at both abutments for ease of identification purposes.
Clearance envelopes for vegetation are required around timber and non-timber structures.
These Standards describe maintenance actions aimed to have a sustained beneficial effect of extending the life of timber structures when undertaken in a regular and systematic manner.
