In order to improve the future traffic quality for the town of Herzogenburg, the existing railroad grade crossing in the “Wiener Straße” (L110) area will be replaced by an underpass. The long daily waiting times at the current railroad crossing (up to 4 hours a day) and the 7,000 vehicles on peak days necessitate this measure.

On 2009/03/16 the official start of construction for the “Reconstruction of Herzogenburg Railroad Station” project commenced. HOCHTIEF Construction Austria carries out the work by order of ÖBB-Infrastruktur Bau AG as part of a consortium.

The underpass - the centerpiece of the contract section - is realized as a “white tank” (watertight tank) across a length of approximately 155 m due to the great groundwater fluctuations and the nearby river Traisen. For this purpose the relocation of the L 110, Wiener Straße is required. The new L 110, spanning approximately 500 m in length, is routed in a westward direction and connected to a municipal road in the direction of the town center. With a roadway width of 7.5 m the new state road meets the present-day traffic standard.

Furthermore, the bid comprises extensive demolition and cutting works, the construction of all earth structures for the reconstruction of the railroad, execution of soil replacement and drainage measures, construction of roads, paths, tracks, railroad bridge and a pedestrian underpass as well as the conducting of the cable runs for the signal, telecom and energy systems.
The new underpass is to be open to traffic by the end of 2009; the overall completion of the works is scheduled for June 2010.
