Unable to answer "How are the footpath and bicycle path laid out here?" – Cycle Path – way/1190735334 via StreetComplete 58.2:

This is a multi-use path. Not a cycleway. Very likely, foot traffic even has the right of way. See the Michigan wiki for more information.

Unable to answer "What kind of parking is this?" – Wintergarden Valet (Park & Ride Lot) – node/10899449712 via StreetComplete 61.3:

Not sure how this should be tagged. This is inside the Renaissance Center, just northeast of the office for a valet service. Not a parking lot.

It is not underground at all. See Mapillary photos.
