The next episode of the longest‑running U. S. primetime series airs on Sunday, marking its 800th episode. The show’s famous family finds themselves in Philadelphia for this milestone, yet the roots of many characters run much farther west, deep in Portland, Ore.  

The creator grew up there and drew on the city’s geography for character names.  Bill Oakley, a former showrunner who moved to Portland after his time on the show, explains how streets like NW 23rd Ave. inspired names such as Flanders, Lovejoy, Kearney and Quimby.  These characters now populate the fictional Springfield in ways that mirror Portland’s own lanes and corners.  

Flanders Street is perhaps the most celebrated link, giving its name to the ever‑cheerful neighbor Ned Flanders.  In 2021, Portland honored this connection by renaming a freeway overpass to Ned Flanders Crossing and adding a bronze plaque with his trademark greeting.  The city’s homage shows how a cartoon can shape local identity as much as the other way around.  

The serpentine Terwilliger Curves on Interstate 5—known for its danger—lent its name to the show’s villain, Sideshow Bob.  Oakley notes that the character’s menacing nature parallels the perilous stretch of highway, a clever nod to Portland’s roadways.  

Evergreen Terrace is another real street that appears in the series, not as a character but as the Simpsons’ home address.  Oakley admits that the specific number 742 does not exist on Portland’s street; the real house numbers begin in the thousands.  The fictional address, though fabricated, has become canonical and beloved by fans worldwide.  

Using street names was not merely sentimental; it helped the writers build a believable world efficiently.  Oakley recalls that naming characters after real locations was a practical solution when creating dozens of surnames for the show’s many residents.  Sometimes names were even pulled from phone books, but only those that felt interesting and unique were chosen.  

This blend of local inspiration and creative practicality shows how a cartoon can reflect its creator’s hometown while shaping the cultural imagination of millions.  Portland’s streets live on in Springfield, proving that even animated families can carry the weight of real places.
