The A100 highway is one of the most important arterial roads in Berlin. Now, the road is set to be extended from the Neukölln intersection through to the Treptower Park interchange to further improve access to long-distance, regional, and city road networks. By 2024, the Federal Government and the State of Berlin will invest over 610 million euros in the A100 extension project to enhance connections between the eastern city districts, the central beltway, and the A113.
The new section of road construction will also provide faster access to Berlin Brandenburg Airport and Adlershof City of Science, Technology, and Media. These improvements will shorten journey times to Dresden, Cottbus, and Frankfurt an der Oder, supporting both commuters and economic activity.
The construction of the brand-new A100 extension requires high-level highway planning and civil engineering expertise. The new 3.2-kilometer stretch of the A100 will have six lanes along its entire length and includes a short section with eight lanes. Almost all of the new road construction will be built in a cutting.
In addition to the top-down construction of the Grenzallee tunnel, the project also involves creating seven intersections with other roads and railroad tracks. The construction of multiple railroad bridges requires close collaboration and coordination between various stakeholders. Track installation planning for the S-Bahn suburban trains, DB AG long-distance trains, and IGB Industriebahn freight trains was also part of the project.
Via the interchanges at Treptower Park, Sonnenallee, and Grenzallee, drivers from the districts of East Berlin will enjoy faster access to the city, regional, and long-distance road networks. The new section of the A100 extension will significantly enhance Berlin’s mobility offering for citizens and visitors alike.
Berlin Brandenburg Airport and Adlershof City of Science, Technology, and Media will now be more easily accessible from the city, as will Dresden, Cottbus, and Frankfurt an der Oder. The A100 project is a vital step in improving connectivity and efficiency across Berlin’s road networks, supporting a modern and sustainable transport future.
From the eastern districts of Berlin, the extended A100 will provide drivers with faster access to the city, regional and long-distance road networks. The three interchanges between Neukölln and Treptower Park will ensure easy access.
