Unable to answer "Does this crosswalk have tactile pavings on both sides?" for https://osm.org/node/1111449231 via StreetComplete 26.2:

Hard to tell which crossing is this about. There are 2 crossings. There is no crossing under bridge.
And I believe both crossings don't have any way of notifying you are near it aside of visual lines drawn on road.
