Review of Alternative Options

The Department of Infrastructure, Energy and Resources (DIER) and its many contractors are well progressed with the construction of the 9.5km Brighton Bypass. The requirement for the Brighton Bypass to be completed in its current location is based on a comprehensive review of alternative routes and relates to the need for improved safety and  increased efficiency of the national highway system in Tasmania. The social and economic benefits of this $176 million project are already accruing to the broader Tasmanian community with many hundreds of people employed on the project.

Extensive environmental and heritage assessments have been undertaken over many decades with more focused assessments occurring over the past two years. Whilst most approvals are in place at this time, a 300 metre section of the northern bypass that enables the crossing at the Jordan River and the associated levee deposit is yet to be approved.

An extensive and sophisticated archaeological investigation was undertaken on the western side of the Jordan River and within the bypass alignment after the discovery of what was thought to be a very old and intact deposit containing Aboriginal cultural material (see fact sheet). The investigation findings confirmed that the site is the oldest known site in Tasmania and amongst the oldest known in Australia and is about 600 metres long and about 60 metres wide.

Once DIER was aware that this site was potentially significant, the design where the road intersects the levee deposit was reviewed. The first generation design would have resulted in significant impacts on the levee deposit. Understanding that this would be unacceptable to the Aboriginal and archaeological community, a bridge design involving 70 metre bridge span was developed to avoid permanent impacts on the levee deposit. The cost of the revised bridge will be approximately $10 million. Once the final results of the investigation were announced another design concession was made to the bridge construction  methodology. At a cost of an additional $2 million the long bridge span will be launched from above rather than lifted from below to avoid impacting the levee.

A short embankment, bridge abutments and multiple span bridge must be constructed outside the levee to complete the crossing. The  documents included here provide a detailed description of the proposed Jordan Bridge design and management options that will allow the long term protection of the portion of the site that is on Crown land including management and interpretation to be determined by the Aboriginal community. An overview of the alternative road alignments that have been considered over recent decades is also included.

To enable the construction of this bridge, a permit to partially destroy is required. This permit application is made under Section 14 of the  Aboriginal Relics Act 1975 and includes a proposal to partially destroy a small portion (4%) of the broader Aboriginal heritage site within which the levee deposit is located. Importantly, this proposal does not result in the destruction of the highly significant cultural deposit contained within the Jordan River levee. The permit application also includes a proposal to protect the remaining 16% of the flood plain that is owned by the Crown.  The remaining 80% of the Aboriginal site remains in private ownership.

DIER accepts that the Aboriginal community is concerned about impacts on this very important heritage site and has proposed a number of measures that come at a high cost but are offered to provide a genuine way forward that will guarantee the preservation of the levee site while still permitting the construction of the Brighton Bypass.
