The NSW Government is planning to upgrade McKanes Bridge over Coxs River on McKanes Falls Road at South Bowenfels. The proposed work includes strengthening of the existing bridge with a safer, stronger and more reliable bridge while still preserving the heritage aspects of the original.
McKanes Bridge is one the NSW’s oldest timber truss bridges.
McKanes Bridge was built in 1893 and is one of only four remaining McDonald timber truss bridges in NSW. Its restoration would ensure one of the oldest examples of a McDonald timber truss bridge in NSW is conserved.
The NSW Government is providing $10 million for the project to ensure the state heritage-listed timber truss bridge continues to serve the community while reducing maintenance needs in the future.
The proposal includes replacing old timber elements with new timber and new heritage sympathetic materials to strengthen the bridge, while still retaining the appearance and design of the original bridge.
Transport for NSW has prepared a Review of Environmental Factors (REF) to determine the environmental and social impacts for the restoration work and was on display from 30 October to 25 November 2019. The REF also explained the proposed restoration work involved, the proposed method to carry out the work and the proposed methods to minimise environmental impacts on the community.
To facilitate the upgrade of the bridge, it is proposed that McKanes Falls Road would be closed to traffic for about 12 months, with a detour in place via Jenolan Caves Road and the Great Western Highway. The detour is expected to add five minutes extra travel time.
The concept design and Review of Environmental Factors (REF) were on display for public comment from 30 October to 25 November 2019. All submissions made during the display period will be addressed and responded to in a submissions report and will be used to further develop the project.
Transport for NSW will continue to keep the community updated as the project progresses
- Upgrade the existing bridge to allow safe use by vehicles up to general mass limit (GML) standard
- Replace the existing timber side rails with a steel traffic barrier over the full length of the bridge
- Restore the condition of the major structural bridge elements to original condition (by replacement or repair)
- Preserve the heritage form of the bridge (truss type)
- The upgrade design is to have as minimal a negative impact to heritage value as possible, while still achieving the above proposal objectives
- Minimise operating costs of the bridge as far as possible while still achieving the proposal objectives.
- Upgrading the structural capacity of the bridge
- Retaining the original McDonald timber truss design
- Upgrading critical structural elements of the bridge with superior and more durable elements
- Upgrading the existing bridge to allow safe use by vehicles up to general mass limit (GML) standard.
