A long-discussed tunnel underneath the Blue Mountains connecting Sydney with western New South Wales has been deemed too long and too expensive.
- NSW government plans two tunnels through the Blue Mountains
- A lengthy tunnel between Penrith and Lithgow is deemed “prohibitively expensive”
- Great Western Highway has become a traffic chokepoint due to disruption on Bells Line of Road
Paul Toole, the Minister for Regional Transport and Roads, said tunnelling through the entire Blue Mountains was not an option.
Two separate tunnels as part of the Great Western Highway duplication project would be a better investment, he said.
