Added pages covering each of the four unsigned Alaska Interstate Highways. Previously the four were profiled on just one Alaska Interstates page. The original page remains, with previous research for the Alaska Interstate System based upon American Association of State Highway and Transportation Officials (AASHTO) and Federal Highway Administration (FHWA) documentation.
With full coverage of all end points, decided to each Interstate onto individual pages. Also added some historical information with research from Newsbank and Newspapers dot com, and added average annual daily traffic (AADT) stats from Alaska Department of Transportation & Public Facilities GIS.
