The Logebach Viaduct is a structure on the Federal Motorway 3 in the Rhein-Sieg district in North Rhine-Westphalia , which spans the Logebach at Aegidienberg (City of Bad Honnef ) and Ittenbach (City of Königswinter ) . It consists of two 160 m long bridges that were built in the 1930s and 1970s.

history

The motorway bridge was built on the site of a bridge that was to become part of a road connection from Hövel over the Laagshof to Ittenbach. Construction of this road started in 1935, but the bridge was blown up in 1937 due to a change in planning.

The northern superstructure now takes up the direction of Cologne and was opened to traffic together with the then Reichsautobahn in 1939. It is a stone arch bridge with a width of 20 meters and a maximum height of 27 meters. The bridge has six intermediate piers that form a total of seven round arches. The original length of the bridge was planned to be 213 meters.

To the south of this original building, in the course of the three-lane expansion of the A 3 in the early 1970s, another bridge was built on which the direction of Frankfurt am Main runs. The girder bridge has a two- web T -beam cross- section and has six pillar axes . The deck slabs of the younger girder bridge and the older arch bridge are structurally connected to each other.

The western section of the bridge lies in the area of the city of Königswinter (district Ittenbach), the eastern section in the area of the city of Bad Honnef (partial district Aegidienberg). Parallel to and 200 m southwest of the motorway bridge is the 173 m long Logebachtal bridge of the same name on the high-speed railway line Cologne-Rhine / Main .
