The NSW State Government Department RMS was renamed Highways Inc in 2016
Desperately needing funds to complete the sinking Pacific Highway between Macksville and Urunga, it decided to cease funding Waterfall Way, after it complete the highway from Dorrigo to Coffs Harbour.
As some compensation it funded the building of a funicular railway.

This was built on the site of the old Syndicate Tramway which allowed timber to be moved from the top of the escarpment to Gleniffer in early twentieth century.
This new railway allowed produce to move to and from the Dorrigo plateau and provided an exciting tourist link, adding to the charm of a visit to Bellingen.
The scale of the system allows cars and containers to move up and down the escarpment.
A secondary advantage was that it stopped the gravel trucks passing through Bellingen town.
Cellular road construction
Methods became available about 2016 to allow cellular construction of roads that allowed use of recycled fill materials rather than newly quarried gravel - see above and following link http://www.prs-med.com/road-construction/road-construction-overview
Hovercraft - jem-mobile
The technology of the new hovercraft vehicles is described in the technology section, but their advantage was to reduce the load on roads and simplify road maintenance.
Much of the maintenance of roads was delegated to residents especially after Bellingen Shire Council ceased to operate.
