Enligt Street View-bilder från 2022 så finns det hastighetsskyltar här, stämmer det fortfarande? Om ja, är det fortfarande 30 i nordlig riktning och 50 i döerlig riktning?

Finns denna path fortfarande?

What type of building is this, residential? Also what type of solar generators are on the roof?
