WIKIPEDIA: Due to the repeatedly occurring weld cracks due to metal fatigue the old bridge had to be replaced after 40 years by a new. Southwest, since May 2009, this is next to the old bridge in a distance of 46 m. Until the completion of the new bridge in the year 2012, subject to authorisation schwertransporte may no longer cross the building. Also, a ban on overtaking, a speed limit of 60 km/h and a minimum distance of 100 m applies to trucks. The right lane was also moved towards the middle of the bridge in a less damaged area. As new construction is a steel composite bridge with a two-part construction over a total of 29.5 m width for the two direction lanes planned. 755 M-long building should have a continuous beams with spans as building system in longitudinal direction of 59 m, 84 m, 103 m, 3 × 107 m, 105 m and 83 m. In the transverse direction, a construction that is rarely performed in Germany will be applied. Superstructure for each only a narrow steel girder height of 4.5 m is intended, to the double-sided cantilevered reinforced concrete road slab with diagonal Struts relies. Over the concrete steel round pillar is planned to combine the two in a distance of 14.9 m arranged racks by cross beams.
