Washington Roads - WA 99



WA 99 is former US 99, which explains the numbering of BC 99 in Canada that now connects directly into I-5. 99 doesn't do much anymore besides be a freeway, expressway, and general arterial in the Seattle-Tacoma area. The freeway's really cool though, an old bi-level six-lane viaduct with some really old signs. That'll be the Alaskan Way page below.

WA 599 is a freeway connector from I-5 to WA 99 south of Seattle (hence the number) and the main alternate to I-5 from southern suburbs and cities into downtown. Here it ends and magically becomes WA 99. WA 99 used to head south at this exit but the shield was removed when the route was decommissioned south through Tukwila to WA 518.
