Thanks Radagast.

There’s a link at the bottom of that page you posted that takes you here (apologies if already posted):

https://www.gcmc.ca/galore-creek-project/

At the bottom of this page are four pdf links. Clicking on the right hand link - Project Info Sheet - will open a pdf showing, if you scroll down, proposed and existing routes from Galore Creek to the highway. This seems to be a current document.
