The article says that Sam Hill "built" the highway. This is only true in the sense that, say, John F. Kennedy "built" the Apollo program (well, a little closer because Hill lived to see the highway completed). He was, indeed the prophet and advocate of the highway, and he had good a bit (mostly politically) to do with building the Oregon segment and (to a lesser extent) some of the Washington segment, but it was not really in his capacity as an actual builder of roads, it was in his capacity as an advocate for good roads. See John E. Tuhy, Sam Hill: The Prince of Castle Nowhere, Portland, Oregon: Timber Press (1983), ISBN 0917304772, especially Chapter 16 "The Long Crusade". - Jmabel | Talk 20:07, 1 August 2010 (UTC)Reply
There are really no appropriate citations in the article. There are also a lot of factual errors and confusions with other later named highways. The Pacific Highway was a very early 1910s auto trail between San Diego and Vancouver B.C. Rather than placing a template on the page, I'll likely do a complete encyclopedic rewrite. — ★Parsa ☞ talk 03:17, 8 February 2012 (UTC)Reply
