I talked to three cross country truckers a few years back, before the first time Hawai'i was ranked 50th in urban Interstate pavement condition, and they all said without any hesitation whatsoever that Hawai'i had the worst interstate road conditions in the nation.  I think Hawai'i may not only be last in this category, but it may be last by a mile (or several poorly paved miles).  Didn't know about the bridges, but I can't say it comes as any surprise.
