I don't want to think about how many billions of dollars it would take to restore the CR&NW right of way.   Even the Chitina to Kennecott piece would be daunting; there is only one bridge still intact and while it handles highway traffic, sorta, I doubt it is up to railway standards anymore.   Much of the CR&NW was barely up to railroad standards in its heyday.   The rest of the bridges have just been allowed to rot away and there is no remaining railroad infrastructure.   Then there is the issue of an entrepot.   Cordova has shown itself to be decidedly uninterested in industrial scale tourism and highway access via Valdez and Glennallen to Chitina wouldn't produce anything like enough traffic.   The ROW does belong to the State and it would be a good thing to develop it into a useful road, but the US hates the idea and the greenies oppose it at every turn, so I suspect 63 miles of very bad road is the best we'll have for a long time.
