That sometimes is the case.  Portland's west hills (as well as other
parts of the state prone to landslide) often leave addresses from one
street (or even a street that no longer exists) connecting to another
street entirely, in some cases quite some distance from the original
road connection.

One of my friends in Salem also lives in a neighborhood that
demonstrates this... the 100 block of Wander Way forms a single L-shaped
block, with the top of the L paralell to the 100 block of 24th Street
SE.  The 200 block of 24th Street is barely long enough to fit a compact
car in before it terminates in a permanent Type III barricade, yet the
200 block has addresses going almost to 300.  The odd side of the 200
Block 24th Street is actually the odd side of the base of the L where
the street leaves the City's path of address interpolation.
