The
Landwasser Viaduct(
German: Landwasserviadukt) is a
single-track six-
archedcurved
limestone railwayviaduct. It spans the
Landwasser between
Schmitten and
Filisur, in the
canton of
Graubünden,
Switzerland.
Designed by Alexander Acatos, the Landwasser Viaduct was constructed between 1901 and 1902 by Müller & Zeerleder on behalf of the
Rhaetian Railway, which both owns and operates it through to the present day. A signature structure of the
World Heritage-listed
Albula Railway, it is 65 metres (213 ft) high, 136 metres (446 ft) long; its southeastern abutment connects directly to the
Landwasser Tunnel.
[1]During 2009, the Landwasser Viaduct underwent renovation work for the first time since its original construction.
