The Dultenaugrabenbrücke is a 444 meter long girder bridge and part of the A 98 . The bridge is an eight-span steel composite structure that was initially opened in 2002 as a crossing with one lane in each direction of travel and received a second bridge superstructure in a further construction phase. It has had two lanes in both directions since 2010.
The bridge is supported by a total of seven reinforced concrete pillars. The field widths are 35.52 meters - 44.40 meters - 53.28 meters - 66.60 meters - 75.48 meters - 71.04 meters - 57.72 meters - 39.96 meters. The superstructure has a box cross-section in the transverse direction with a constant construction height of 3.0 meters. The reinforced concrete deck is prestressed in the transverse direction without joining .
