Designed by Hermann Schürch, it was built between late June 1913 and early July 1914 by Müller, Zeerleder und Gobat, for the Chur–Arosa railway.

Due to the difficult geological conditions in Schanfigg, a total of 18 tunnels and 40 bridges needed to be created between 1912 and 1914 for the privately built Chur-Arosa line.

At each of these points, instead of a bridge with many multiple openings, a sensational reinforced concrete structure arose with a large single span.

The risk that piers might be undermined by the course of the river could thus be met successfully; since the completion of the Chur-Arosa line, the Gründjitobel Viaduct has only rarely been harmed by erosion.

The falsework, which had already been used in the construction of the Halen Bridge in Kirchlindach, Bern, originated, as with the Langwieser Viaduct, from Richard Coray of Trin.
