Hi Kari
Impressive POV and great contrast.
The line of the dexk bridge take us trough the hills.
p.s.
a small correction the bridge is made in mansonry way from stone and mortar much earlier than the age of concrete.

To ruisc_pt: Construction technique for Wiesen viaduct
Thanks Rui,
<A HREF="http://www.rhb-unesco.ch/pdf/2a4_e.pdf">This document</A> says on the last page that construction is "line-of-thrust arch with concrete blocks". But certainly it's not made in a modern way of reinforced concrete. Kari
