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.
The new crossing gives a much improved bridge to bridge circuit walk of 6.4km via the Penrith Valley Bridge
