The arch bridge is located near Kirchheim in East Hesse and spans a valley with the Wälsebach and the state road L 3159, which connects Kirchheim with the northeastern district of Reckerode , at a maximum height of 40 m above ground .

The gradient slopes continuously to the south on the bridge. The layout of the route in the bridge area is curved and has a radius of 5100 m.

The Autobahn 7 runs in the immediate vicinity, and the railway line in the Krämerskuppetunnel passes under it.

ICE 1 on the Wälsebachtal bridge

Due to a subsoil with chimneys due to the weathering of the solution in the red sandstone ( sinkhole area ), no pure girder bridge was used. At the southern and northern end of the structure, a sinkhole was spanned with a hollow beam as a foundation. The middle of the bridge has a chain of four arched bridges, each with a span of 127.5 m, which cross two further chimneys. The superstructure is elevated with reinforced concrete pillars on the arches. The superstructure consists of a chain of 28 single-span girders . This enables individual bridge segments to be replaced later. The cross-sectional shape is a single-cell reinforced concrete box with inclined webs, prestressed in the longitudinal direction . In addition, the deck is prestressed in the transverse direction. With a superstructure width of 14.3 m, the total span is 3 × 27.9 m + 2 × 25.5 m + 4 × (5 × 25.5 m = 127.5 m) + 3 × 25.5 m = 721, 2 m.

In the planning phase, the bridge was in planning section 15 of the central section of the new line.
