You are not wrong about road benefits.  But the Feds built the railroad and under totally different circumstances and motives.  They had no OSHA, standards other than what it took to lay track & bed  that was twenty feet wide, not 60 and didn't give a whit about streams, swamps and the ecology in general.  And there was gold in Fairbanks.  The only "resource" in Juneau is corruption and they do a fine job of exporting that already!  We can't take any more of their brand of prosperity!
