Construction progress Combination solution Karlsruhe

Work on the Karlsruhe combi-solution will continue in the new year. Drivers in Karlsruhe must therefore prepare themselves for further diversions due to new construction work in numerous districts.

On the western side of the city, construction workers are still digging new excavation pits so that more tunnel walls can be built. For this reason, tests are still being carried out in some construction sites to ensure that the underground work is not hindered by groundwater that could penetrate into the construction sites.

In the east, the interior construction of the railway tunnels is in full swing. In the railway tunnel, the tracks are already being fastened by laying a ballast bed on which the rails will then be laid. In this way, both sides of the track can soon be completed.

The interior work also continues at the metro stops. Elevators and escalators are in-stalled and the walls are clad in light concrete. The walls, which are given a special look by roughening, are in progress and will soon be completed. This gives a first impression of what the underground stops will look like in the future.
