History

The southern, the place Wommen facing half of the bridge, was built 1938-1940. Because of World War II were completed in the northern part, only the abutment. Due to the division of Germany, the building first went into operation, and remained until 1990 locked. Immediately after the turn, not only the restoration of the old red sandstone bridge was tackled, but the new design for a parallel run second viaduct, as the German Unity Transport Project to improve the traffic situation on the motorway route of the A came up four special meaning. The construction of the second bridge on the carriageway Kirchheim took place from 1992 to 1994.

The Viaduct is a large vault series bridge with 17 arches, the Pfeilerachsabstände be 16.525 to 18.05 meters. In each direction two lanes with hard shoulders are available.

The northern half of the bridge was built in 1992 to 1994. The dimensions were taken analogous to the southern half. However, the supporting structure is made ​​of 80 cm thick reinforced concrete arches, on which 25 cm thick reinforced concrete cross slices at a distance of 3.8 m are arranged. The deck has a thickness of 25 cm and is monolithically connected to the transverse slices. The pillars have a hollow cross section of reinforced concrete and steel stairs are inside with fitted. The 14 middle piers are founded on bored piles 1.3 m in diameter and up to 25 m length. The elaborate design and 5000 m² of natural stone facing construction costs were approximately 27.3 million DM, which corresponds to 5742 per square meter bridge surface DM and based on the area was more than twice as expensive as in similar bridges with conventional prestressed concrete bridges.

For both bridges, the view has been preserved in sandstone. In the new building, however, was omitted glamor of subpages sheet for cost reasons. Instead, a colored concrete was applied.
