PBOT: Burnside Street History

Burnside Street originally was named B Street as part of the "Alphabet District" in northwest Portland that was laid out by Captain Couch. B Street extended from the waterfront to 16th Avenue, where it joined Washington Street to continue westward. What we call Burnside Street west of 16th today was considered an extension of Washington, not B Street. This combination of B and Washington Streets formed the principal east-west thoroughfare from the river and led to Tuality Road, a rough road winding through present-day Washington Park over the west hills to the Tualatin Plains.

...

Washington Street west of 16th became Burnside Street in 1933 when the city systemized the street names and numbers. A couple of years later, property owners petitioned to change Burnside's name to Bonneville, but historical organizations protested and the name remained Burnside.
