These are freeway access ramps and structures with not footpaths.

There is a gate that blocks access to the second part of the road.

The trail was wildly inaccurate. Strange how this wasn't fixed earlier, but now it is! Hooray!

Fixed typo in trail name

this path allows non-motorized access, not just foot traffic.

this forestry road is gone, probably due to reforestation in this area.

there is no access past the gate, this is closed private property.

"Thaa" is an old spelling. On the Swiss topo map and on all modern signs it is spelled "Taa". https://www.winterthur-glossar.ch/app/default/pub/fw.action/wine.article?ce_id=27&ce_name=GeneralArticle has some background.

it shouldn't show up like this on english maps. none of the other swiss cities with umlaut characters do.

this is the elevation from the swiss national topo map.
