Also in 2006, the series "Bridges and Tunnels" presents interesting engineering structures that have recently been redesigned or rebuilt: 8 bridges and 3 tunnels.
As a replacement for the nearly 80-year-old chain bridge over the Lahn in Nassau in the course of the B260, a new steel bridge was built using the old portals.
An elegant and very light steel bow-arched bridge at Elstal, north of Potsdam, transports a pedestrian and bicycle path over the four-lane B5.
At the site of a historic river crossing over the Ruhr in Hattingen, a new building in steel composite construction for the B51 and a double-track tram has been erected as a replacement for a discontinued steel bridge from 1936.
With a 1150 m long steel composite bridge with one-piece superstructure, the Südharzautobahn A38, which is still under construction, is being run from Göttingen to Halle (Saale) near Berga via the Thyratal.
In the area of Schleswig-Holstein and Mecklenburg-Western Pomerania, south of Lübeck, the new A20 crosses the scenic and ecologically very sensitive Wakenitz lowlands on a nearly 300 m long steel composite bridge.
The 723 m long Lockwitztal bridge in steel composite construction in the course of the new A17 to Prague south of Dresden is not only technically an unusual building, but outstanding in terms of design.
Instead of an old stone bridge with 12 arches from the year 1833 over the flood plain of the Unstrut near Sachsenburg, a similar building with 12 reinforced concrete arches was erected for the federal roads B85 and B86 to be converted.
By installing additional pair of columns and a load-distributing, with the steel cover plate connected by welded wood dowels connected reinforced concrete slab bridge built in 1982 on the DB tracks south of the junction Karlsruhe-Durlach A5 could be strengthened.
East of Hessisch Lichtenau for the under construction A 44 between Kassel and Herleshausen the approx. 284 m long Walbergtunnel and the 544 m long Hopfenberg Tunnel built using shotcrete construction.
To relieve the passage through the village from Pfullingen south of Stuttgart in the course of the busy B312, the 1180 m long Ursulabergtunnel with a closed vault cross-section as an impermeable concrete construction has been constructed in an open construction.
