The Vorpommern Bridge crosses the state road L 22 northeast of Rostock city centre over Warnow. The L 22 is a 4-streaked road with 2 lanes per direction,
which is also the most busy road in Rostock and Mecklenburg-Western Pomerania with approx. 42,000 car/24h, making it very important for the city and the surrounding area
by Rostock.
The Vorpommern Bridge was erected from 1983 to 1986 as a 3-field-fielded prestressed concrete bridge with a cross-section of a two-cell hollow box that advocates towards the center supports.
The end fields were built on the ground, while the midfield in the open stem was concreted lamellar by lamellar by both central pillars. The bridge has spans of 35.50 m/74.00 m/35.50 m.
The road runs in a top of the entire building.
Within the first 15 years after commissioning, a steadily increasing increase in midfield deflection was observed. In the mid-1990s, tests and recallocations found that the bridge's clamping reinforcement was too small in the original statics. As a result, the structure of the bridge was reinforced in 1998 by external tensioners located in the hollow boxes.
Despite this gain, which has caused a temporary improvement with a decrease in deflection, midfield deflection has been slowly but steadily increasing since then. In 2019/2020, a recaltlement of the building was compiled on the basis of the federal reaccounting guideline, which, however, cannot prove the deformations and deflections as a result of own and expansion loads as well as temperature actually measured at the building. As a result of this recaltlement, the structure was classified in stage 3, proof class C of the settlement guideline on a one-line system. These results have been confirmed by the test engineer.
