 McCutcheon had promised that the line would be extended northward from Armstead to Dillon, Montana that year, the first step in completing a connection to the NP's trackage at nearby Twin Bridges.No further construction took place, however, in part due to G&P legal difficulties in securing right-of-way between Armstead and Dillon.Simultaneously, though, the NP began to realize the engineering difficulties and limited economic potential of its proposed Salmon River route, and local G&P officials began to discover that the local traffic potential was actually far less than anticipated.
