Overview

• The 16th section of the A100 motorway, connecting Neukölln to Treptower Park, is now scheduled to open in early September 2025, delayed from mid-year.
• The latest delay is attributed to supply bottlenecks for components required for electronic traffic sign bridges.
• Construction began in 2013 with an initial budget of €450 million but has since ballooned to €720 million, with completion originally expected in 2021/2022.
• The extension features a 386-meter tunnel and a 2.3-kilometer trench up to seven meters deep, with junctions at Grenzallee, Sonnenallee, and Treptower Park.
• Environmental groups, including Aktionsbündnis A100 stoppen, continue to oppose the project, citing concerns over sustainability and calling for investment in greener mobility alternatives.
