Tiefenwinkel overpass

N03,76 Re­hab­ili­tation

The Tiefenwinkel overpass rehabilitation project essentially involved the design and implementation of the following works during 2012: connection of individual piers to create diaphragms, removal of existing cantilever edges and construction of new cantilever edges with traffic barriers, shear strengthening of deck at piers, placement of approx. 10 cm-thick reinforced-concrete topping, replacement of bridge waterproofings and surfacings, installation of new expansion joints, concrete repairs, replacement of bearings and tensioning of new tie rods, alterations to side-span areas and landscape works. Given the urgency of the works to the severely damaged, slender bridge piers, the project was designed and implemented within a very short time window.
