Frequently Asked Questions

An Initial estimate to investigate, design and construct a pedestrian bridge was around $500,000.  

Once detailed design work had started it was discovered that further unexpected engineering work would need to be undertaken to construct a stand-alone pedestrian bridge increasing the cost estimate to around $1 million.  

 As this amount doubled the expected cost, a revision of the options has been made.

Around 600 vehicles (80 peak hour) and 25 pedestrians (10 peak hour) use the bridge on a daily basis.

Six options were considered by both councils in 2021/2022:

• Pedestrian bridge installed on the south side of Erskine Bridge.
  
  
• Pedestrian bridge installed on the north side of Erskine Bridge – “dog-leg” alignment to avoid a large tree.
  
  
• Pedestrian bridge installed on the north side of Erskine Bridge – straight alignment which would require a large tree to be removed.
  
  
• Pedestrian bridge bracketed to the north side of Erskine Bridge.
  
  
• Traffic lights to control separate movement phases of pedestrians and vehicles.
  
  
• Dedicating the existing bridge as a pedestrian bridge only and constructing a  new low-level ford crossing in Steele Street for vehicle traffic.

High level cost estimates and associated advantages and disadvantages were explored when assessing each option.

The most cost effective option is the traffic light installation (around $400,000), which fits with the previously anticipated budget. 

 All other options were between $700,000 and $1.1 million.

The traffic light option was the only option that provides a controlled dual use of the existing bridge for vehicle access as well as pedestrian access.

There are no detrimental impacts on the river environment and vegetation as no works are required in these areas to install the lights.

This solution can be solar or battery powered and includes minimal infrastructure representing a minimal carbon footprint. 

The main disadvantage to this option is that there may be some minor queuing required at times while pedestrians or vehicles are on hold.

Road users adhering to traffic light signals cannot be guaranteed.

Subject to both council's budget processes including securing of grants, installation of traffic lights could be competed in the 2022/2023 financial year.

The bridge is heritage listed. The bridge could be closed with no further maintenance undertaken on it.  It would then gradually fall into disrepair.

An alternative crossing was proposed for Steele Street (option 6 above)

Both Mount Barker and Murray Bridge Councils have been progressing options for a number of years. Tthe complexity of the width of the bridge, the approaches to the bridge, the heritage restrictions, and community expectations have all contributed to it taking time to develop and prepare preliminary designs and cost estimates.

Once consultation has concluded, funding can be included in the 2022/23 budget for detailed design and construction. 

Each Council will receive a report advising of the outcome of this consultation and seeking endorsement to continue exploring the other options.
