Barham Koondrook Bridge

Roads and Maritime Services, in partnership with VicRoads, is continuing the restoration of Barham Koondrook Bridge over the Murray River. The NSW and Victorian Governments are funding this $17 million essential maintenance work to ensure the bridge will continue to meet current vehicle loads and volumes, as well as the growing needs of the local and travelling community into the future.

Addendum Review of Environmental Factors

The restoration of the Barham Koondrook Bridge has been modified to include:

  • A new pedestrian walkway attached to the outside of the existing upstream bridge trusses and lift span
  • Installation of lighting on the bridge
  • Installation of a new lift span maintenance ladder
  • Removal of the existing bridge pathway barrier
  • Removal of a tree.

The addendum is now available to view or download from the project documents page.

Traffic moved on to temporary bridge crossing

Traffic and pedestrians are using a temporary bridge crossing while the historic Barham-Koondrook Bridge is restored.

Removing traffic and pedestrians from the work site gives workers full access to the bridge without disruption and delays to the community.

The temporary bridge will be removed after completion of the restoration work. We expect road users to be using the temporary bridge for up to 12 months.

Pedestrian walkway

Roads and Maritime Services has received approval from the Heritage Council of New South Wales to build a pedestrian walkway on the Barham-Koondrook Bridge.

The restoration of Barham Koondrook Bridge will now include installing a new steel bridge walkway. Building a new walkway, in keeping with the heritage values of the bridge, will mean pedestrians will be completely separated from traffic.

Project background

Roads and Maritime has been restoring the historic lift span bridge since April 2012. The work has included mechanical repairs to the lift span and replacing the NSW approach span.

This restoration work is ensuring the bridge will continue to meet current vehicle loads and volumes, as well as the growing needs of the local and travelling community into the future. Without this work, restrictions such as load limits would have to be imposed, restricting accessibility across the river.

The Barham Koondrook Bridge is one of the oldest lift span bridges on the Murray River. It is listed on the NSW State Heritage register and has to be retained for its heritage value.

Next stages of work

The next stages of work involve: 

  • Replacing the Victorian bridge abutment (support at the end of the bridge), approach span and pier
  • Replacing the two timber truss spans and deck
  • Painting and mechanical upgrade of the lift span towers.

Environmental assessment

The review of environmental factors was displayed for community comment in March 2016 and a submissions report completed.

The submissions report and review of environmental factors can be viewed in project documents.

Temporary crossing investigations

Community and stakeholder engagement has been an essential part of planning for restoration work on the Barham Koondrook Bridge. Feedback received during consultation about bridge closures showed a strong preference for Roads and Maritime to provide a temporary crossing solution for the next stages of work.

Six temporary crossing options were investigated, including options suggested by the community, and are as follows: 

  • Option 1 – Cobwell Street (via Murray Parade)
  • Option 2 – Cobwell Street (via Vine and Dalton streets)
  • Option 3 – Thule Street (next to Barham Koondrook Bridge)
  • Option 4 – Wakool Street (via Murray Parade)
  • Option 5 – vehicular ferry at Noorong Street (via Murray Parade)
  • Option 6 – Punt Road (via Teague Street)

A map is available in the community update.

Options 1 and 4 were considered unsuitable as there is not enough room for heavy vehicles to turn safely.

Option 2 was considered unsuitable as heavy vehicles would need to be diverted on to narrow residential streets, requiring significant intersection upgrades and road widening.

Option 5, the ferry, was considered unsuitable as it would be unable to meet vehicle capacity during peak times.

Option 6 was considered unsuitable due to the significant amount of tree clearing and road construction involved. This option is also close to the Koondrook Primary School.

Recommendation for a temporary crossing – Option 3 Thule Street (next to Barham Koondrook Bridge)

Option 3 is the preferred option as it:

  • Suits the movements of heavy vehicles better
  • Reduces moving traffic through residential streets
  • Environmentally, only disturbs previously disturbed areas
  • Needs less road works and intersection upgrades
  • Provides better pedestrian access.

An analysis of Option 3 is shown in the table in the community update.

The impacts from the temporary bridge are:

  • A narrower width of 4.2 metres, restricting the movement of wide loads such as farm machinery across the bridge. The existing bridge allows for 4.8 metre wide loads
  • Single lane with possible traffic signals
  • The removal of up to 19 trees to build access roads to the temporary bridge
  • Construction period of five months to build the temporary crossing, including three intersections. Traffic controls and some noise would be associated with this work
  • Changes to road and property accesses in both Barham and Koondrook to ensure the safety of motorists
  • No lift span, restricting river traffic such as paddle steamers having access under the bridge. The temporary bridge structure would be 300mm lower than the existing lift span in the lowered position. And the height restriction would be determined by uncontrolled river height.
  • Possibly four closures of the temporary bridge when the old truss spans are removed from the existing bridge and the new truss spans installed. This is for the safety of workers and road users because of how close the temporary bridge will be to the existing bridge
  • In use by motorists for up to 12 months.

The cost estimate for Option 3 is about $2.3 million using Roads and Maritime’s existing temporary bridge infrastructure. Using a temporary bridge that is owned by Roads and Maritime is a lower cost option than hiring and using an external supplier’s product. The temporary bridge will carry the same loads as the existing bridge.

Roads and Maritime has carried out an economic analysis which shows significant project delivery and community cost savings with this temporary crossing solution. These savings would come from a more efficient work program, reduced safety risks, reduced traffic control, and much less disruption and delays to the community.

The temporary bridge would allow the community to carry on as usual – minimising economic impacts and keeping the connection between both communities.

While the temporary bridge crossing will impact river traffic and wide loads, Roads and Maritime believes that the benefits mentioned above make this a viable and worthwhile proposal to proceed with.

The temporary bridge would be removed after completion of the restoration work.

No temporary bridge crossing

Without a temporary bridge the following would occur:

  • About two years to finish the restoration work compared to 12 to 15 months
  • Up to 15 days of bridge closures
  • A detour of around 56 kilometres during closures which adds another 40 minutes to a motorist’s journey
  • Ongoing delays of up to 20 minutes on most days
  • Traffic controls in place 24 hours a day
  • Night work to avoid some closures and delays on weekdays and weekends that impact businesses. Noise would be associated with this night work.
