A7 in Hamburg: Mega traffic jams through tunnel blocking until Monday morning!

Hamburg, Deutschland - Last Friday evening, July 18, 2025, the full closure of Autobahn 7 in Hamburg began, which will last until Monday morning, July 21, 2025, at 5 a.m. This measure affects the section north of the Elbe tunnel, between Hamburg-Schnelsen and the Hamburg-Nordwest triangle. This execution is not a spontaneous decision, but the result of the necessary technical upgrades of the noise protection tunnel, which has been in use since 2017 without interruption. In order to have a good knack with security, the IT components and the software of the tunnel are renewed after eight years of operation, explains ndr .

The weekend is shaped by long traffic jams. On Saturday, the traffic to the north had grown north from Hamburg-Waltershof to about 10 kilometers. But there were not only patience games for drivers on the A7: the exit Hamburg-Eidelstedt and other alternative routes were also heavily overloaded on the A23 towards Heide. Alternative routes, such as the A1, were also affected by stagnant traffic due to the increased traffic volume. Before the actual closure, traffic jams of up to 15 kilometers between Hamburg -Heimfeld and Schnelsen were already formed on Friday afternoon, which also spoiled the traffic situation.

planned measures for traffic safety

The need for full closure is not only a technical nature, but also has a security -relevant background. In addition to the technical upgrade, the fire brigade will use this opportunity to carry out an extensive exercise in the tunnel area. This security measure will be part of the comprehensive strategies in order to be able to guarantee the safety of passengers in the event of an emergency, according to autobahn.de .

But that's not all! After the weekend work, there will also be a night closing on August 16, 2025, which will last from 10 p.m. to 10 a.m. on the following day. This blocking is necessary to dismantle the old components and carry out other necessary exams.

diversions and traffic information

For the outstanding state, far -spacious diversions via the A1, A21 and B205 were recommended. These measures are particularly important for travelers in the direction of the North Sea, which should be prepared for longer travel times, especially on well -known storage routes such as AS Neumünster Süd or B205. If you are traveling outside of the usual travel times, you could benefit from lower storage.

also during the holiday season, in which nine federal states have already sent their students into the summer vacation, this block could hit some travelers. Therefore, the traffic experts advise you to take enough drinks and pay attention to traffic information to ensure a tolerable journey.

It remains exciting about the further development of the A7, since numerous further closures are due in the coming months. A look at the planned measures confirms this:

The drivers will have to be patient for some time while the A7 is further expanded and modernized. Find out more about the noise protection measures and the legal basis at the Ministry of Transport via Trid.trb.org .
