You can always do a public records request with the City of Spokane or the Washington State Department of Transportation to request bridge drawings. Sometimes it is difficult to get access to the actual plans, but since the bridge is being replaced it might be worth trying.
by any chance do you know if there's a way to find the blueprints for this bridge (Post Street bridge in Spokane)?
