About this project
The project includes upgrades to the road approaches and improved safety with the improvement of existing traffic barriers to current Australian standards
Funding for this project is part of the NSW Government’s Bridges for the Bush program. The initiative is a commitment from NSW Government to improve road freight productivity by replacing or upgrading bridges over the next five years at 17 key locations in rural and regional NSW.
Bridges for the Bush is an investment in critical infrastructure to remove a number of significant freight bottlenecks on the state road network and to improve the safety and reliability of regional bridge structures.
Features of the existing bridge
The bridge over Bemboka River at Moran's Crossing was built in 1937 and is 7m wide and 92.2m long. It consists of seven spans, each measuring 7.45m, 13.90m, 16.5m, 16.5m, 16.5m, 13.90m and 7.45m.
Consideration of options
Two design options were considered for the upgrade, one on either side of the existing bridge. A preliminary Environmental Investigation (PEI) was undertaken to assess the impact of both the upstream and downstream design options.
The investigation assessed a number of areas including hydrology, air quality, flora and fauna (including platypus), noise impacts, Aboriginal heritage and non-Aboriginal heritage.
In September 2012 consultation began with local residents and stakeholders to discuss the project.
As a direct result of consultation with local landowners additional biodiversity investigations to further evaluate the potential impacts of both designs on the local platypus colony were undertaken.
Following the community consultation and review of the PEI potential risks, recommendations and conclusions, Roads and Maritime made several design changes to the original upstream and downstream options to minimise the potential environmental impacts.
The PEI was updated and the impact of both revised design options reassessed against a range of factors including environment, heritage, community, constructability and land acquisition.
After analysis of the environmental investigations and risk assessment, the decision was made to widen the bridge on the downstream side.
This option was found to reduce the impact on local flora and fauna (including the local platypus habitat), would not require expensive realignment of utilities, would minimise the amount of land acquisition required and would reduce the number of affected land owners.
