WSDOT has added a series of county maps to their online collections, including this 1982 sheet of Snohomish County that shows the Monroe bypass. A windmill interchange with SR 522 is quite intriguing, I would've thought a standard trumpet would have been the preference.

EDIT: Another one, with SR 509 cutting through Des Moines as mentioned earlier.
