The viaduct is 150 metres long, 24 metres high and has seven arches, each with a clear width of 14.50 metres, which rest on six pillars and two massive abutments. It consists of approx. 14,000 m³ of concrete and is clad with approx. 3800 m³ of granite stones. The construction enabled the old steel bridge, built between 1869 and 1871, to be replaced and the railway tracks to be extended to three tracks.
