Nelligen Bridge replacement

Roads and Maritime Services is planning for a new bridge over the Clyde River at Nelligen.

The new bridge would be built upstream of the existing bridge ensuring a safe and reliable Kings Highway crossing of the Clyde River at Nelligen.

Once the new bridge is open the existing Nelligen Bridge would be removed.

The NSW Government has allocated $1.5 million in 2016/17 to further develop the project.

Updates and announcements

The feedback period for the concept design and environmental impact assessments for the proposal has closed.

Submissions are currently being collated and will be addressed in a Submissions Report which is expected to be available early next year.

Project background

The existing Nelligen Bridge was built in 1964 and forms part of the Kings Highway crossing of the Clyde River at Nelligen. During routine bridge inspections we identified some of the supporting concrete pillars under the bridge had deteriorated. The bridge has been assessed and is still able to safely carry normal traffic loads, however the pillars will weaken over time and the bridge will require significant future maintenance or replacement.

The primary objective of the project is to ensure we retain a safe and reliable crossing of the Clyde River at Nelligen without imposing speed or weight restrictions.

To do this the project investigated four options for repair or replacement of the bridge against a range of functional, environmental and socio-economic criteria, and consulted with Eurobodalla Shire Council and local residents.

The option to provide a new bridge to the north (or upstream) of the existing crossing was considered to be the best option because it would minimise impacts on residents and heritage. The preferred option report is available for information.

Environmental impact assessment documents

The environmental impact assessment documents were displayed for community and stakeholder feedback from Friday 14 October until Friday 18 November. Documents on display included the Review of Environmental Factors and the Environmental Impact Statement which contain specialist studies and investigations about biodiversity, heritage, visual impact, noise and vibration and water quality and hydrology. Feedback will be used to further develop the proposal and will be addressed in a Submissions Report which is expected to be available early next year.

Review of Environmental Factors

The Review of Environmental Factors assessed the potential environmental impacts of the proposal and identifies ways to manage and mitigate these impacts.

Environmental Impact Statement

The Environmental Impact Statement assessed the potential environmental impacts of the proposal specifically on the SEPP 14 wetlands located within the project site. This area is shown on the concept design map.

Project benefits

A new bridge to the north of the existing crossing would improve safety by providing:

  • An improved curve on the eastern side of the bridge
  • 3.5 metre wide lanes
  • 2.5 metre wide shoulders
  • Safety barriers between the road and footpath.

A new bridge built to the north would provide:

  • 100 year bridge design life
  • Improved boat mooring space in the Clyde River.
