Hochstrasse Oldenburg, Prestressed concrete highway bridge in Oldenburg, Germany

Hochstraße Oldenburg is a 1,450-meter prestressed concrete bridge carrying Bundesautobahn 28 between the Oldenburg-Eversten and Oldenburg-Kreyenbrück junctions. It crosses the Hunte, the Küstenkanal, the Osternburger Kanal and several city streets. The structure has separate decks for each direction, divided into three sections by two expansion joints, and was built from 1979 to 1981.

The bridge was built between 1979 and 1981. Its 84 deck sections were erected using movable falsework, not prefabricated segments. The main bridge deck was cast in a single pour of 3,900 m³ of concrete over 42 hours.

The bridge structure represents a period of infrastructure expansion in Lower Saxony during the early 1980s, marking technological progress in German engineering.

The bridge carries Bundesautobahn 28 between the Oldenburg-Eversten and Oldenburg-Kreyenbrück junctions, with an extra lane in each direction between the Marschweg and Kreyenbrück ramps. It is a motorway structure with no pedestrian or cycle path, so it is seen from the banks of the Hunte, the Küstenkanal or the Osternburger Kanal beneath it, or from the parallel city streets it crosses.

The main span extends roughly 98 meters without intermediate supports, allowing the river to flow freely beneath without obstruction. This engineering solution was notable for bridges of this size built during that period.
