I could stand to be corrected, but I don't believe this is a 'new' one. When I last spoke to staff about this earlier in the fall, I was told that they were only relocating ramps from some stops that had to be moved due to long-term construction. I think there were between 2-4 available this fall; and then a lots will become available whenever they re-do King, those ones will all be re-deployed since King's stop extensions will be made permanent.
I'm under the impression the City won't be ordering more temporary ones in the near-term, only building permanent new ones as opportunities arise, and then relocating the temporary ones as they are no longer required. I will hasten to add, I didn't specifically ask about anything beyond 2023.
