As I understand it (having noticed and heard it discussed in a just-captured video of a drive through the area), it was added some time in the first half of 2024. I'd checked all the numerous orthoimagry and street-level photo sources in iD and JOSM (the vintage of which for this immediate area all predate this year), and (unsurprisingly) it doesn't appear in any of them. Additionally, there are no uploaded GPS traces that are new enough to track it. (Nor do proprietary map providers or their imagery have it.) Therefore, I left a note here for future mappers once a survey, imagery or GPS traces are available to properly map it, or if another mapper would like to make the change "black box".
