The Seattle Department of Transportation is using a new digital method to print all kinds of traffic signs, and they are making old street signs available for purchase.
As the Seattle Department of Transportation (SDOT) installs new street signs, the department will store the old ones and make them available to anyone for $5 – $15 (depending on sign and condition). The inventory list of signs is not up to date, so you might consider just going to the warehouse to browse and see what is available.
Here is the story of how Seattle’s street-naming system began.
SDOT’s street sign replacement program is made possible by Bridging the Gap, the nine-year transportation maintenance levy. By this year of 2016, every neighborhood will see new, brighter and bigger street signs. Here is a look at the SDOT Sign Shop and how they work.
Signs that are currently available can be purchased at the City’s Surplus Warehouse. For additional information call the warehouse at 206-684-0827.
The Surplus Warehouse is located at:
3807 Second Ave. South
Hours open to the public:
11 a.m. to 4 p.m.
Tuesday and Thursday only (closed holidays)

I took a look at that link. Lots of interesting odd things I can buy and some cool bargains on office stuff too. Thanks 🙂
And don’t forget the University of Washington surplus store, though it may be less convenient to access because it is only open to the public on Tuesdays. They send out info on Twitter, of what’s available.
