The Neutorbrücke is a road bridge built in Ulm at the beginning of the 20th century , which crosses Neutorstraße over the tracks of the railway lines to Stuttgart and Aalen and connects the city center with the Kienlesberg and the Michelsberg. It has been a listed building since 1990 .
description
The Neutor Bridge was built between 1906 and 1907 on behalf of the Royal Württemberg State Railways according to the plans of the Stuttgart engineers Levi and Büttner by the machine works Esslingen to cross the tracks of the Filstalbahn and the Brenzbahn . It has two lanes and a sidewalk on both sides outside the porters.
With its two pylons standing on stamped concrete pillars and the curved upper chords of the side girders, it looks like a chain bridge. Its iron, riveted half-timbered construction rests on two pillars and spans three openings. The iron pylons standing above the pillars are connected to a portal with an openwork cross bar rounded at the bottom. The Ulm coat of arms is attached to the apex of the arches with a gold-plated crown. The upper ends of the pylons are decorated with neo-Gothic turrets and gilded spikes.
Contrary to the external appearance, however, the 112.2 m long structure with three openings of 28.90 m - 54.40 m - 28.90 m is a cantilever bridge with a Gerber girder . The outer 44.2 m long bridge girders extend from the abutments over the respective piers as cantilever girders 15.3 m into the main opening. The remaining opening was closed with a 23.8 m long tanner beam. The Gerber joints are in the lower chord. In order to allow the upper chords to pass through without any visual interruption, non-load-bearing blind rods connected via elongated holes were inserted above the joints . The two lattice girders have a pillar center distance of 7.0 m, the sidewalks lying on laterally cantilevered consoles are 2.30 m wide. The superstructure consists of an iron structure with longitudinal, transverse and main girders, on which concrete road and pavement slabs, on which the asphalt road surface was applied, rest.
The Neutorbrücke is similar to the larger Friedrichsbrücke in Mannheim , built in 1891 and destroyed in 1945, as well as the somewhat larger Salzachbrücke , opened in 1903 between Laufen and Oberndorf near Salzburg . The Liberty Bridge ( 1896) in Budapest and the Eiserne Steg (1912) in Frankfurt am Main have a similar design .
The Neutor Bridge was renovated between 1987 and 1989 and placed under monument protection. The new tram tracks leading to the Science City were given an adjacent bridge construction, which cannot be used for motor vehicles.
