[edit] NPOV

Current article refers to the brick building protruding into the Viaduct as "disconcerting." This is a value judgement; I think it's a rather cool feature of a truly urban freeway, built with tight tolerances. As such, I'm editing to be neutral. ---N, Tacoma, WA

Some confusion with US 99 vs. I-5 near Seattle. US 99 seems to have stayed on the old route. That makes two PSH 1 alignments.

Some intersections with separate US 99 in 1965
  • SR 518 Riverton Heights
  • US 99 Temporary [now SR 99] Foster
  • SR 181 [Boeing Access Road] Duwamish
  • SR 509 [now SR 99] Duwamish River
  • US 10 [Denny Way] Seattle
  • SR 513 [North 130th Street??] North Seattle
  • SR 525 Martha Lake

US 99 was deleted in 1969, and partly replaced by SR 99. But apparently the southernmost piece of SR 99 was SR 514, so it's unclear where US 99 left I-5. I-5 opened to SR 516 in 1962, and was posted as I-5/US 99, so that may be where. That gives no number for current SR 99 from old SR 514 to SR 516, except for the SR 509 concurrency. (SR 161 ended at I-5.) US 99 and I-5 seem to have joined at SR 526/SR 527.
