The three-way highway junction Funkturm (radio tower), which joins the highways A100/A115 in the Berlin district of Charlottenburg-Wilmersdorf, is the junction which connects Berlin’s urban area to the A115 which leads out of the city of Berlin to the outer circular highway A10 and Berlin’s surrounding area. The intersection contains a number of structures which can only be used to a limited extent because of their condition, or can be expected to deteriorate in the foreseeable future. Traffic safety is only partly assured because of technical defects in the roads, so the junction needs to be altered and reconstructed.

The intersection consists of approximately 2 kilometers of roads on highways A100 and A115 with transport infrastructure, 25 bridge structures, 3 railway lines which must be crossed and other civil engineering structures (sound protection walls, supporting walls, traffic guidance and control systems, road sign gantries, drainage systems) and numerous cable and pipe systems which must be taken into account.

The client is the Senate Department for the Environment, Transport and Climate Protection. In January 2018, the developer role was assigned to the national public sector road infrastructure company for the unified Germany Deutsche Einheit Fernstraßenplanungs- und -bau GmbH (DEGES).

The junction is used by approx. 200,000 vehicles per day, making it one of the busiest road sections in the whole of Germany, and it is of major importance for national and international road transport to, from and through Berlin. The project is being planned according to the BIM method.
