The Canberra Times has a story on proposed busway plans from Simon Corbell which will inflict further damage on O’Connor Ridge (by tunnelling and cutting through it), but also open a real possibility for light rail (which I have long maintained would struggle with the grade on Belconnen Way, and am rather pleased to see that estimation vindicated).
So will the Save The Ridge people put the greater environmental interest ahead of their backyards?
UPDATED: Brendan has put out a media release in which he echoes many of your concerns.
