Glemstalbrücke, Bridge near Markgröningen in Baden-Württemberg

The Glemstalbrücke near Markgröningen is a 348-metre prestressed concrete railway bridge on the Mannheim–Stuttgart high-speed line, crossing the Glemstal valley northwest of Stuttgart. Its deck runs on an 8,000-metre curve and climbs eastward at 11.5 per mille. The main span is 58 metres, widened from the standard 44 metres, and the structure reaches up to 54 metres above the valley floor, the highest bridge on the line.

The bridge was planned from 1973, when an initial route alignment foresaw a structure over 400 m long and up to 60 m high. On 15 April 1975, the councils of Markgröningen, Möglingen and Schwieberdingen rejected the new line in principle. Construction ran from summer 1985 to March 1987, and in February 1986 low temperatures forced a temporary halt.

The bridge is accessible only to railways and serves high-speed train traffic on the Mannheim-Stuttgart route. Visitors can view the structure and the valley from nearby paths or viewpoints in the surrounding area.

The bridge features a gentle curve with an 8000 meter radius, allowing trains to travel smoothly at high speed across the structure. A large excavation site called Eichholzer Klinge nearby was used as a dumping ground for earth removed during the railway construction.
