Hi, Dear Andie,
I asked both Oregon licensure board and NCEES. So far what I got is as follows.
1. NCEES tells:
Taking the "other module" of the PE Structural Engineering exam once a candidate has already passed one is not allowed by policy, unless it is required by a state board.
2. Oregon board told me that they will discuss that during next meeting...
So, I think, it is still possible for a SE (bridge) passer apply SE license in Oregon but with more paperwork and passing SE (building) exam. If you are working in Oregon and want to get SE in Oregon, you better take SE (building).
