Speaking of Lithgow, I was driving from Sydney to Bathurst a few weeks ago visiting from WA. Gee that road is very windy and slow. I suspect there was more traffic given Bells Line from Windsor was closed due to the severe weather. Has there been discussions of a faster connection between Penrith and the Blue Mountains?
The Kuranda Range in North QLD would be a similar setup, but a bit shorter. There’s been talk of a tunnel through the range since Adam was a boy.
