Yandhai Nepean Crossing

The NSW Government has built a new pedestrian and cyclist bridge spanning the Nepean River between Penrith and Emu Plains. Roads and Maritime Services has delivered the new bridge to provide a safe crossing for pedestrians and cyclists over the Nepean River and improve connections to existing and future shared paths, including the Great River Walk.

Bridge named Yandhai Nepean Crossing

In June this year Roads and Maritime Services invited the local community to name your bridge (PDF, 1.86Mb). We had over 300 submissions through this consultation. Roads and Maritime was committed to fully engaging and involving the community in the process to name this new landmark in the community.

The bridge naming committee met in August to consider and choose a name for the new bridge, based on both Roads & Maritime and Geographical Names Board guidelines and criteria. The name ‘Yandhai Nepean Crossing’ was chosen.

The word ‘Yandhai’ contains elements of Darug language, and means ‘walking in past and present’. ‘Nepean’ has been kept in the name to signify the bridge’s place. ‘Crossing’ (instead of bridge), signifies both the bridge’s modern purpose and the historical use of this location along the river as a significant crossing.

More details can be found in the Nepean River Bridge Public Naming Submissions Report (PDF, 693Kb).

Bridge opened 28 October

Yandhai Nepean Crossing was officially opened on Sunday, 28 October 2018 by the Hon Gladys Berejiklian MP, Premier of New South Wales, and the Hon Stuart Ayres MP, Member for Penrith.

Hundreds of locals attended the opening to embark on the first public crossing of Yandhai Nepean Crossing.

Project background

Community members campaigned for a safer crossing over the Nepean River for pedestrians and cyclists as the current path on Victoria Bridge has no barrier between the narrow footpath and road traffic. During the strategic stage and concept development, a clip on shared path as well as a stand-alone pedestrian and cyclist bridge directly next to Victoria Bridge on the southern side were investigated. A structural feasibility study was completed in 2010, which determined the Victoria Bridge would not have sufficient structural capacity to accommodate a clip on shared path structure. An adjoining bridge next to Victoria Bridge would adversely affect flooding and impact on the heritage structure.

The final location of the bridge was pushed further south away from Victoria Bridge to avoid hazards and other local constraints. These included heritage, access to and around property and the submarine high pressure gas mains on the southern side of the bridge which supplies Blue Mountains residents with gas.

In mid 2012 a number of community information sessions were held to assess the best location for a new crossing of the river. Six crossing locations were ranked against key criteria identified during the community consultation workshops including safety, function, cost and community.

The location south of Victoria Bridge was considered the safest and most appropriate. The preferred bridge design and location was chosen following extensive community consultation, as it best addressed environmental, engineering and community constraints.

The project was approved in November 2014, and in December 2014 Roads and Maritime started early site preparation work which involved the demolition of the remaining derelict building on the Log Cabin site at Memorial Avenue, Penrith.

The detailed design of the bridge and invitation of construction tenders to build the bridge was carried in 2015 and early 2016. Roads and Maritime has contracted Seymour Whyte Constructions Pty Ltd to build the bridge in May 2016.

Changes during detailed design of the bridge

Changes during detailed design of the bridge

The original concept design considered a curved design, however during the detailed design phase, it was revised to incorporate a straight triangular truss with a gentle vertical curve. The straight truss bridge option will still provide a large span, generous width and unique structure that will be an attractive landmark for the area.
The straight option will provide:

  • A more efficient structural design which reduces the amount of steel needed by 20 per cent
  • An easier fabrication process, with less welding and more similar pieces of steel
  • A simplified construction methodology that will reduce bridge self-weight loads
  • Reduced risks during construction of the bridge
  • Reduced carbon footprint, by using less steel and energy during construction.

The estimated cost of the bridge construction is $49 million. This estimate has increased from the original estimate during the preliminary concept design, due to the complex nature of the long span structure and construction methodology, as well as the relocation of overhead high voltage electrical lines crossing the river. However, the straight truss bridge option has helped to keep the overall cost down when compared to the original curved design.
