I see "Stop #74270" listed on https://kingcounty.gov/en/-/media/king-county/depts/metro/schedules/pdf/03282026/rt-239.pdf -- that's mapped 50m north -- https://openstreetmap.org/node/4113093804/history. It's missing a route relation though (which I don't have experience in).

Now the question is: has the stop moved after the 2024/2025 construction?

Might need a physical survey, or wait until maps are updated.
