Put simply, the main [highway] across the blue mountains, the "Gateway to Western NSW", is a nightmare! It may not be as hard to traverse as when Blaxland, Wentworth and Lawson first made the journey but it's not far from it. Speed cameras are everywhere and it is stop start, speed up, slow down the entire way.
Rural people deserve a better route to their capital city. Sydney-siders demand a better route out out-to the country. This billy-goat track is not just slowing traffic, it's crueling our economy.
Yes, I'm reticent to suggest digging a tunnel through the entire thing but realistically, I believe it is the best long-term solution. It would open up so much more of NSW that over time the benefits would be remarkable (and profitable).
Obvously, it wouldn't be cheap. How would we pay for it? One way would be to invite an off-shore partner, say from Shanghai,
If we decide to do it, which prima facie, I think we should, we shouldn't skimp. It should be 4 lanes wide for cars plus space for an east/west rail link. It may seem extreme now, but in 50 years it will simply, be.
