The Logebachtalbrücke is a 173 m long railway bridge at route kilometer 41 of the high-speed line Cologne – Rhine / Main . The bridge crosses the the nature reserve Seven Mountains lying Logebachtal and therefore bears his name.
course
The structure rests on four pillars and reaches a height of up to 22 m above the valley floor, analogous to the height of the neighboring motorway bridge ( Logebach valley bridge ) on federal motorway 3 . The bridge lies between the Ittenbach and Aegidienberg tunnels in the area of the city of Bad Honnef or on the boundary of the city district of Aegidienberg (southern part) and the area of the city of Königswinter (northern part).
history
planning
The planning status from the end of 1995 provided for a length of 175 m for the structure.
At the end of 1997 the planned length was 173 m. In mid-1998, the Federal Railway Authority advised Deutsche Bahn that the bridge would have to be built differently due to the new Habitats Directive . Regardless of this, the planned length according to the planning status from mid-1999 was unchanged at 173 m. This corresponds to today's length.
construction
The bridge was built with a telescopic arm .
On July 10, 2001, the gap was closed on the bridge, the last section of the high-speed rail section being welded.
To compensate for the ecological interference in the Siebengebirge nature reserve, two 600 m² feeding ponds for kingfishers were created.
