Ottensen macht Platz — Hamburg's Five-Month Car-Free Street Experiment, Curtailed by a Court and Made Permanent

Ottensen macht Platz was a traffic experiment by the Altona district office in Hamburg, part of the EU Cities4People project. From early September 2019, parts of Ottensener Hauptstrasse, Bahrenfelder Strasse, Grosse Rainstrasse and Erzbergerstrasse were converted into an almost car-free zone for pedestrians and cyclists, with delivery access in set time windows.
The Institute for Transport Planning and Logistics at TU Hamburg ran traffic counts and surveys and published the evaluation in September 2021. As summarised by the Boell Kommunalwiki, about 80% of residents and visitors saw improvements in traffic safety, quality of stay and conditions for pedestrians and cyclists, and nearly 80% rated the effect on the district as good or very good. Residents of the core area reported less noise, while adjacent streets saw slightly more.
The business picture was mixed: about 70% of businesses reported delivery difficulties, many reported falling sales, and overall 44% rated the project positively and 40% negatively; almost half of market traders saw their location or sales as somewhat improved.
On 27 January 2020 the Hamburg administrative court (15 E 5647/19) granted suspensive effect to an objection by two businesses, judging the signage likely unlawful for lack of a sufficient legal basis, and the trial ended after five instead of six months. On 20 February 2020 the district assembly voted for a low-car zone; a preferred variant was adopted in May 2022 and, per the district, construction of the permanent 'freiRaum Ottensen' (planned 20 months, four traffic loops) was announced in April 2026.
Caveat: the traffic-count figures from the full TUHH report were not independently verified here; survey figures are as reported by secondary summaries.
