Hamburg's Köhlbrand Bridge bans heavy trucks to prevent collapse risks
Heavy Trucks Banned from Key Port Route to Protect Aging Bridge
From this point forward, certain trucks will no longer be permitted to use a critical highway link through Hamburg's port. The restriction applies specifically to oversized transports requiring special permits and weighing more than 44 metric tons, according to the city's economic authority, as well as reports from the Deutsche Presse-Agentur and the Hamburger Abendblatt. The measure aims to reduce structural strain and ensure the bridge remains operational.
For decades, the bridge has served as a vital artery for port traffic, with around 32,000 vehicles—including countless trucks bound for the A1 and A7 highways—crossing it daily. Most routine traffic will remain unaffected for now.
Deterioration of the Köhlbrand Bridge Accelerates
The new rule follows a recent structural inspection by the port authority, which identified additional damage—particularly to load-bearing components and access ramps. Issues include cracks, spalling concrete, and altered material properties.
Heavy transports place an outsized burden on the structure. Officials note that a single oversized load can exert forces many times greater than a standard truck, making these restrictions essential to prolonging the bridge's service life.
Previous measures have already been introduced: since 2012, trucks have been banned from overtaking, and in 2019, a minimum 50-meter following distance was imposed.
Who Is Affected?
The latest restriction targets only a small segment of traffic. Regular freight transport will largely continue as usual, as most trucks fall below the weight threshold.
- Ban applies to trucks over 44 tons
- Primarily impacts heavy and extra-long transports
- Standard traffic up to 40 tons remains permitted
- Combined transport (e.g., rail-truck) up to 44 tons still allowed
The bridge will thus remain accessible to the bulk of port traffic, though specialized hauls will now need alternative routes.
Criticism and Delays in Replacement Plans
Industry representatives have long warned of the bridge's declining condition, and political figures are now questioning the timeline for its replacement. Built in 1974, the Köhlbrand Bridge is slated for eventual demolition, but construction of a new structure is not expected to begin until the early 2030s.
