- Replacement of the existing columns to a stronger steel material (outer skin to mimic timber) and positioned closer to anchor blocks removing the need to remove or remediate the existing footings.
- The bridge deck has been raised up to be level with the town square paving, eliminating ramp access issues.
- The clear width access between columns and between the toe-boards on the deck will be increased from .85 metres. The full deck width will be utilised of 1.2 metres and there will be a minimum clear width between handrails of 1.1 metres (or 1.8 metres should the wider bridge design be selected).
- Feature lighting attached to the main cabling profile and decking which allows for ease of maintenance.
Who originally built the bridge and why?
The bridge was constructed by the 22nd Construction Regiment (renamed 22nd Engineer Regiment in 2013), Royal Australian Engineers, Australian Army in 1985.
This Regiment consists primarily of reservists and in particular provides aid to local communities and emergency services during disaster response. The Regiment is also deployed overseas for humanitarian and peace-keeping missions.
Council had been looking for ways to better connect the residents of the east to the main street and decided that lobbying the Army to construct the bridge as a training mission was the best way forward. After a few years of correspondence, the bridge was built and officially opened on 10 November, 1985 by the Hon. Wendy Fatin MP, Member for Brand.
The project looked like it would not go ahead as the Federal Government agreed only to fund travel and labour. Alcoa of Australia Ltd stepped in to show their community support by not only donating materials, but also providing accommodation for army personnel during their stay in Pinjarra.
Shortly after the bridge was constructed, Arup were engaged to provide remedial works and strengthening, which included installation of a second main cable and larger anchor blocks.
