Temporarily Repairing the Maroder Canal in Bremerhaven
Bremerhaven's iconic canal, connecting the Old and New Harbors, is facing a critical phase due to its deteriorating condition. The canal, nearly a century old, has been affected by the shipworm, a marine parasite, and the impacts of historical changes in the Weser River and the broader harbor infrastructure [1].
In response to this situation, the city of Bremerhaven has announced temporary measures to ensure the safety and accessibility of the area during the renovation process. The first phase of construction is set to begin on Monday, March 31, and will involve the closure of the eastern parking bridge multiple times between 6:30 AM and 4:30 PM [2]. A detour route for traffic participants has been established via Van-Ronzelen-Straße and Hans-Scharoun-Platz.
To maintain stability during the construction, horizontal supports will be installed in the canal. These supports will be placed just below the water surface and will secure the stability of the quays. As a temporary solution, the cost of these measures is approximately 240,000 euros, to be borne by the city of Bremerhaven [3].
During the second phase of construction, scheduled to begin on or after Monday, April 7, in the area of the western pedestrian bridge, the installation of supports is expected to take about two weeks. Once completed, the parking bridge will become accessible again [4]. However, it's important to note that ships will not be able to reach the Old Harbor during the repairs [5].
Cars and pedestrians will still be able to cross the canal, but ships will not be able to pass through. This temporary situation will not affect the Sail event, which will feature a cultural stage on a pontoon in the harbor basin, with local artists performing, and a competition for local school bands or soloists [6].
The comprehensive renovation of the connecting canal will start next year. The cost of the renovation will be determined in the summer, according to Mayor Melf Grantz (SPD) [7]. Despite the renovation being completed too late for the Sail event, the city of Bremerhaven will spend around 200,000 euros on the alternative Sail program [8].
The dilapidated condition of the canal is a result of the shipworm and the historical changes in the Weser River and the broader harbor infrastructure. Since the 19th century, the Weser has undergone twelve human-led deepenings to accommodate maritime traffic, which caused severe ecological damage and likely affected the condition of connected waterways and canals in the area, contributing to dilapidation over time [1].
As Bremerhaven continues to grow as a major northern European port, it is plausible that local authorities and port administration are considering or undertaking modernization and renovation measures to improve infrastructure and efficiency [3]. For more detailed or updated information on renovation efforts, consulting Bremerhaven’s municipal or port authority publications would be advisable.
