The steps up from the river (level -1) end higher than the road (level 0), but not up to the height of the bridges (which would be level 1, I'd suppose). The shorter set of steps here lead back down to the road level.

Unable to answer "What kind of building entrance is this?" – node/3461830774 via StreetComplete 61.3:

This node is placed at the entrance to a lift - but directly opposite the lift, there's a padlocked door - I'm not sure where it goes. The node could have been intended to mark that, not the lift

Unable to answer "Does this street have a sidewalk?" – הלל (Residential Road) – way/20708409 via StreetComplete 60.0:

This section is part of the crossroads, so no, I guess? But there is a pedestrian crossing, so perhaps yes?
