Not a marked crosswalk. Technically—and legally—there's an unmarked crosswalk at every corner/intersection, and I've tried to include such crossings to avoid weird results, so routing applications don't send anybody to the far corner to cross a street or conclude there's no connection between one sidewalk and another on an adjacent block. Most such unmarked crosswalks at T intersections around here have no ramps or tactile paving on the "top" of the T.
