The Sacred Buffalo Vision by Robert J. Juneau and Robert C. Juneau pg.124

The matter finally simmered down to the fact that the Highway Commission were forced to find a place to put large sums of money, or it would revert to the Government, and lose this money to the state. For this reason, the Highway Commission turned their eyes to Glacier County. First, for the reason that on account of the fact that lands on Indian Reservations may enjoy the benefit of 100% of Federal Aid construction, and secondly, because Glacier County joins Glacier Park, it would be a benefit to the entire state, as well as other states, to have the entrance roads to Glacier Park in first-class shape. After the proposition was put up to Glacier County, it was only a short time until the proposed Federal Aid roads were released by the owners and Indian allottees, and a comparative short time when Federal Aid roads were under construction. Glacier County has now, approximately 60 miles of Federal Aid highway complete, and nearly as much on which construction has been started, or will be started within a short time. I feel this is not only a great asset to Glacier County, but also to the state, particularly on account of the fact that this highway is all at the entrance of Glacier Park. I have talked to many tourists who have been over it, and they are all surprised how fine this road is, and are all very much pleased with it.
