The Ko’olau Mountains were the backdrop to bike riding, skateboarding, and kickball on my childhood street. The grey strip near the mountain base is the H3 freeway and didn’t mar the soaring emerald green as a child. It’s an intrastate Interstate Highway, built with Federal funding to link the Pearl Harbor Naval Base with the Kaneohe Bay Marine Corps Base and satisfy national defense needs. Though its an engineering marvel and, at $1.3 billion, one of the most expensive Interstate Highways ever built, its also sore on my nostalgic eyes.
