North Portland is a diverse mixture of residential, commercial, and industrial areas.
Nicknames for it include "NoPo" and "the Fifth Quadrant" (for having been the odd-one out from the four-cornered logic of SE, NE, SW, and NW, prior to the 2020 arrival of South Portland).
During World War II, a planned development named Vanport was constructed to the north of this section between the city limits and the Columbia River.
[3] In 2004, the MAX Yellow Line opened along North Interstate Avenue.
The light rail line parallels I-5, stopping short of crossing the Columbia River.
