Hawthorne Avenue Bridge
Posted November 17, 2009, by Michael Goff (michael [dot] goff [at] odot [dot] state [dot] or [dot] us)

Hawthorne Boulevard (and thus the bridge) was named after Dr. J.C. Hawthorne, the cofounder of Oregon's first mental hospital and early proponent for the first Morrison Bridge.

This is from the Wikipedia article for the Hawthorne Bridge

Who was this bridge named after? Maybe Charles Hawthorne WWII
