The Dease Lake line was starting to appear increasingly uneconomical. There was a world decline in the demand for asbestos and copper, two main commodities that would be hauled over the line. As well, the Cassiar Highway that already served Dease Lake had recently been upgraded. Combined with the increasing construction costs, the Dease Lake line could no longer be justified. Construction stopped on April 5, 1977. Track had been laid to Jackson Creek, past Fort St. James, and clearing and grading were in progress on the rest of the extension. It had cost $168 million to that point, well over twice the initial estimate. The trackbed can be seen on Google Earth all the way to Dease Lake, via the small towns of Leo Creek and Takla Landing.
