B 289, Kauerndorf Bypass

Project objectives

Design, construction and initial operation of the Kauerndorf Bypass.

Project description

The B289 Kauerndorf Bypass project includes the pre-cut junction west with high slope cuts, retaining walls, excavations, and an underpass, as well as the tunnel with two rescue tunnels and ancillary structures. The pre-cut junction east features additional retaining walls and excavations, while the mass concept includes spoil deposition and a conveying system. A key aspect of the digital planning tools is the comprehensive application of the BIM method across all planning stages. The tunnel runs close to developed plots.
