So to see how traffic was, I mapped out Stadium Mall to Nuuanu on Google Maps. Amazingly, Google told me to take the H3 over the Koolaus then go townbound on the Pali. 30 minutes said Google.
I was thinking of taking Moanalua Highway towards Tripler, but Google said that route would take 15 minutes longer. So while a longer route, Google was correct and now I’m early.
