Shoalhaven River South Bound

Specific challenges – Short TermNowra – The southbound bridge over the Shoalhaven River at Nowra is narrow at only 5.55m wide and only 4.6m high, restricting access for OSOM vehicles, is not suitable for HML access and also has a Poor Bridge Health Index.

Specific Priorities Complete planning and commence construction of a new Shoalhaven River crossing.

25

Currambene Creek North Bound

Specific challenges – Short TermNowra to Jervis Bay Road – The northbound bridge over Currambene Creek is not suitable for 26m B-Double operation at HML. Specific priorities– Short TermInvestigate options to upgrade the northbound bridge over Currambene Creek to be suitable for HML access.Specific - Medium term priorities Construct replacement or upgrade existing bridge on the northbound carriageway over CurrambeneCreek to cater for HML B-double access.

Clyde River Bridge Batemans Bay

Specific challenges – Short TermBatemans Bay – Narrow bridge over the Clyde River (6.09m). Clyde River Bridge is not suitable for HML access. Bridge over Clyde River has a "Poor" Bridge Health Index. Specific priorities– Short TermCommence planning for the renewal or replacement of the bridge over the Clyde River at Batemans Bay.

27

Wagonga Inlet Bridge Narooma

Specific challenges – Medium termNarooma – The Wagonga Inlet Bridge is very narrow at only 6.09m and has a 4.5m height limit due to the truss design and is not suitable for HML access. Specific - Medium term priorities Develop options for a new bridge over the WagongaInlet balancing anticipated freight and regional travel demand against the cost of infrastructure and improving road safety. Investigations should include a bridge and improved road alignment on the bridge approaches suitable for 26m HML B-Double Access.


28

Brogo River Bridge

Specific challenges – Medium termBrogo River Bridge is a narrow bridge only 6.09m wide and is a 26m B-Double HML constraint. The southern approach has very poor alignment and is also a constraint for 26m B-Doubles. Specific – Medium term priorities Commence planning to improve the crossing over the Brogo River, including addressing the constraints and road safety hazards on the southern and northern approaches.


29

Tuross River Bridge

Specific challenges – Long termTuross River Bridge is not suitable for HML access.

Specific – Long term priorities Develop options to replace the Bridge over Tuross River or strengthen the bridge to enable 26m B-Double HML access.
