Rosental Viaduct in Friedberg (March 2005)

The Rosental Viaduct (vernacular: 24 halls) is a historic railway bridge north of the Friedberg station entrance on the Main-Weser Railway .

topography

The Rosental Viaduct crosses the Usa valley between Friedberg and Bad Nauheim . The historic viaduct dates from the construction period of the Main-Weser Railway between 1847 and 1850 and was replaced in 1982 in its function by a parallel, modern concrete structure without the historic bridge being demolished.

Construction

Rosental Viaduct

The historic Rosental viaduct is a monumental stone - arch bridge with padded bow of red sandstone. It was built by the Mainz architect Peter Hochgesandt . With 24 arches - hence its second name 24 halls - it spans the Usatal over 275 meters at a height of 16 meters. The 24 arches are divided into three groups of eight arches each by polygonal pillars . The platforms of the pillars provided employees of the railway with safe protection from approaching trains. The sheets are, moreover, of conical separated tapered pillars, whose cornice fix the sheets. The style of the building is based on Roman aqueducts . A profiled parapet band forms the upper end .

This very representative version of the bridge is said to be due to the fact that it is in the immediate vicinity and in the field of vision of Friedberg Castle , which was the residence of the Grand Dukes of Hesse-Darmstadt when the Main-Weser Railway was built.

Almost parallel runs a lower (12 m), shorter (270 m) and also double-track arched bridge ( Rosental Viaduct II ) in a simpler design for the Horlofftalbahn, which opened in 1897 . This stone bridge with nine arches has replaced a truss bridge from 1897 since 1937.

Monument protection and legal situation

The Rosental Viaduct is an important cultural monument in terms of traffic engineering according to the Hessian Monument Protection Act . The bridge is unique in this size in such artistic execution in Hesse.

Nevertheless, it was planned for demolition by a plan approval decision of the then Deutsche Bundesbahn from 1976, which regulated the construction of the new concrete bridge, which it replaced operationally. The standards for dealing with cultural monuments were then far lower than they are today.

Since the planning approval decision was issued according to an older legal situation, it does not expire, as would be the case today under Section 75 (4) VwVfG . The legal successor of the Deutsche Bundesbahn, Deutsche Bahn AG , still holds a legal title to demolish the cultural monument.

In terms of planning law, it is therefore obliged on the one hand to carry out the demolition, because a plan approval decision that has been used must always be carried out in full by the developer. On the other hand, the social framework and the appreciation of cultural monuments has changed so much in the last 30 years that the right may have to be viewed as forfeited and the railway would then be obliged to change the original plan in accordance with Section 76 VwVfG in favor of maintaining the Rosental Viaduct to let.

Current usage

In the mid- 2000s, it was planned to build Hesse's largest photovoltaic system on the Rosental Viaduct . For this purpose, wooden scaffolding was erected on the viaduct and earth moving work was carried out. Only shortly after the start of construction, the project was stopped by the building authorities of the Wetterau district due to lack of stability after heaps of earth had slipped off. Since then nothing has changed in this situation, the fallow land is slowly growing over again.
