Bosrucktunnel full extension and general renovation of the eastern tunnel tube

In 1983 the first tube of the Bosruck Tunnel was opened to traffic. This was completely refurbished in the course of the full expansion with the addition of a second tunnel tube.

Construction of the Bosruck Tunnel

Within six years, the western tunnel tube of the Bosruck tunnel was rebuilt with all additional relevant construction measures such as the construction of cross passages, conversion of the portal buildings, construction of galleries and work on the architectural design of the portal buildings.

From old to new

The existing tunnel was also completely refurbished during this period. The renovation included on the one hand the removal, disposal and restoration of the inner shell in the area of the pressurized mountains and on the other hand the connection of the newly built cross passages in the existing tunnel tube, the complete renewal of the roadway (substructure, superstructure and concrete roadway), upgrading of the intermediate ceiling and the Drainage system and expansion of the fire-fighting water pipeline.

In both cases, the entire electrotechnical equipment was implemented, refurbished or expanded.
