The Aichtalbrücke is a road bridge built from 1979 to 1983 on the four-lane federal highway 27 between Stuttgart and Tübingen in Baden-Württemberg and crosses the valleys of the Aich and its north-western tributary Bombach.
Geographical location
The Aichtalbrücke stands east of the Schönbuch between the villages of Neuenhaus in the west and Aich in the east (districts of Aichtal ). Its northern end is on the Pfaffenhau ( 362 m above sea level ). Then the bridge spans the Baumbach. The middle of the bridge is on the Geißhau ( 360.5 m above sea level ). The bridge then leads over the Aich. Its southern end is on the Steinenberg ( 383.1 m above sea level ).
About 1.9 km further east-northeast, an older, two-lane bridge crosses the Aich along the 312 federal highway .
description
The bridge is 1,161 m long and 27 m wide and runs in a large arch with a curve radius of 1,500 m. It crosses the Bombach at a height of 48 m and the Aich at a height of 50 m.
It consists of two parallel beams bridges (per carriageway a) each having a prestressed concrete - hollow box with a constant cross-section.
Their field widths are 3 × 51.0 m - 80.0 m - 8 × 51.0 m - 65.0 m - 84.0 m - 65.0 m - 6 × 51.0 m.
The two girder bridges are designed as continuous girders with fixed points on the pillars in the middle of the bridge on the Geißhau. On the other pillars, the bridge is supported on point tilting plain bearings. The reinforced concrete - pillars are hollow and have a constant cross-section.
The bridge was built using incremental launching. At that time it was the longest clocked bridge in the world.
The bridge was planned by Leonhardt, Andrä und Partner and Polensky & Zöllner and executed by a consortium of R. Besemer, G. Epple and Polensky & Zöllner.
