The Marble Bridge is a road bridge on the Splügen Pass above Splügen in the Rhine Forest in the Canton of Graubünden . It is considered to be one of the most classic road structures in Graubünden.
history
The commercial road over the Splügen Pass was completed in 1823. First the road from Splügen ran in a direct line on the right side of the Hüscherabach through the ravine upwards to the south. In 1834 violent storms destroyed numerous bridges, roads and paths across the region. As a result, the route of the road was relocated to the west and serpentines up the steep slope, far from the dangerous brook.
In this context, the marble bridge was built as a representative building with financial support from the city of Zurich. The flat bridge vault was made of white marble, which was extracted from a quarry a little further up the valley nearby ( ▼ ). Splügner marble was also used in the construction of the Milan Cathedral and was used as road gravel in the Rhine Forest.
On the east side of the marble bridge, the new road met the old one, the route of which, as long as it has not slipped, can still be seen in the terrain. The side barriers are made of granite. The marble bridge is 15 meters long and the carriageway is 5 meters wide.
The small marble deposit used belongs to Mesozoic deposits in the Pennine region of southern Graubünden. At Alp Rhäzüns , a light marble was quarried in small quantities, but it was mainly used for quarry stones and gravel.
