From what vantage point did Goethe draw his sketch of the aquaduct and is it accessible now?
Errr.... My culture does not reach the Goethe sketch which you mention. AFIK, an aquaduct is a bridge for a water channel. Landwasser is famous for a railway bridge (viaduct) built in 1902, i.e. 70 years after J.W. Goethe's death? Can you rephrase your question?
Oops. Same question but Wildener Brucke, I think over the Viamala Gorge, south of Thusis, sketched in 1788 by Goethe.
The Wildener Brücke (the remaining one, of the original two) is on the Viamala Trail. Closest access by postal bus, stop at "Zillis, Viamala-Schlucht".

Click on the blue bus stop icon, click on the grey box "Zillis, Viamala-Schlucht". You get the box of the Swiss transport system. Just add any departure station in Switzerland, and the desired day and time of departure or arrival. Have good boots, and don't wander away from the trail, it is quite steep there!
