Due to a lack of steel: Lessing Tunnel will remain closed until December!
In the heart of Altona, a change in traffic routing is causing a lot of conversation and a little patience among drivers. The Lessing Tunnel will reopen to traffic on December 3, 2025, but only partially. The lockdown was originally scheduled to end at the beginning of November, but due to unforeseen difficulties and delayed steel deliveries, the reopening has now been postponed by a few weeks MoPo reported.
Residents will have to wait until the full opening on December 20th; The tunnel currently remains completely closed to car traffic. However, pedestrians and pushing cyclists can still pass. The backlog on Holstenstrasse and Stresemannstrasse has already led to long waiting times.
Construction work on the road bridge
At the same time, maintenance work on the “Julius-Leber-Straße” railway bridge is also underway. These measures are necessary in the short term due to the need for renovation in the bridge area for long-distance and regional traffic. Construction began on September 6, and up to 400 tons of steel will be used to reinforce the structure, reports the German railway.
A complete road closure is expected from November 17th to December 1st. A partial closure has been in place since September 6th. The pedestrian and cycle path will remain passable throughout the construction period, although cyclists are encouraged to push their bikes. In order to better mark the diversions, appropriate signs and digital displays will be put up.
Noise reduction and construction times
In order to keep the annoyance of residents as low as possible, Deutsche Bahn uses modern, noise-dampened equipment. The work takes place in two shifts from Monday to Friday, between 6 a.m. and 10 p.m. There are breaks on weekends to minimize construction noise. Travelers who would like to visit Hamburg-Altona train station during the work must expect possible short-term timetable changes and should inform themselves in advance.
In summary, Hamburg Altona is facing another challenging month on the roads before the situation should ease with the planned completion of construction work on December 20th. Until then it's time to be patient and give way!
