Hochbahn rebuilds Ohlsdorf U1 platform and bridge by October

Hochbahn is closing the U1 from 13 July to 14 October 2026 between Fuhlsbüttel Nord and Lattenkamp (replacement buses) and rebuilding the Ohlsdorf platform, which is over 100 years old, from scratch, together with the roughly 45 m U-Bahn bridge over Alsterdorfer Strasse; the bridge over the Alster is also being repaired and track and systems renewed. At the same time it is shifting the U1 tracks outward at Sengelmannstrasse so the future U5 can run in the centre, allowing a cross-platform interchange; the U5 is due to run there from 2029 to City Nord and to Bramfeld from 2033. After service resumes on 15 October, trains pass through Ohlsdorf without stopping until 28 October 2026. The date is a placeholder: it marks the end of these non-stop passes; no costs are given. Announced on 22 June 2026. (LOK Report, 28 Jul 2026)
