Explore Yukon Highways
This map is from a 1972 brochure, "travelling yukon", published by the Yukon Dep't of Travel and Information. The information on the highways reads:
The Robert Campbell Highway
Yukon Highway 9 was opened in 1968 and now provides an alternatiive route to the Klondike through 372 miles of newly-opened mountain wilderness. Photo and fishing opportunities are tops and the highway is actually 20 miles shorter than the Alaska Highway if you're heading to Dawson City. The highway starts at Watson Lake and runs northwest for 230 miles to Ross River, a small community six miles north of the highway on the Canol Road. At Mile 264 a 17-mile side road leads to the new town of Faro. Highway 6 heads west for 142 miles, joining the Klondike Highway (Hwy. 2) just north of Carmacks.
The last sentence is incorrect - it should read "From the junction at Mile 230, Highway 9 heads west for another 142 miles, joining the Klondike Highway (Hwy. 2) just north of Carmacks."
See the Canol Road page for that information from this brochure.
