Notes
  • Significance: The Hawthorne Bridge is the oldest extant vertical lift bridge in the United States. It is the oldest of Portland's Willamette bridges, initiating the replacement of earlier swing spans. Designed by Waddell & Harrington, as the firm's earliest surviving lift bridge it reveals how Harrington managed the transition from Waddell's South Halsted Street prototype to the "standard" vertical lift form. Reconfiguration of its approaches, replacement of its wooden deck by steel, and other modifications embody 90 years of highway engineering history.
