this website is a marvel, the fact that there are over 100 year old concrete ships still floating makes me wonder if there are concrete or nonmetallic ships still being constructed today for secondary purposes like carrying garbage or as bridges

  The 520 and I-90 bridges in Seattle are built with floating concrete pontoons.

    Ooh! Are we talking about infrastructure projects in Washington State? This is a nerd-snipe headshot.
    Washington State has four of the top five floating bridges in the world!
    I-90 is actually two bridges, the second and fifth longest in the world.
    SR-520 is the longest.
    Hood Canal is third.
