This has set up a project page on the homepage strassenbau.niedersachsen.de:
When will it be demolished?
Demolition of the old bridge will begin in 2025. The challenge: unlike newer bridges, the current bridge does not consist of two parts, but is a single structure.
If everything goes according to plan during demolition, work on the new bridge will begin in the same year. Construction is currently expected to take two and a half years.
What will the new bridge look like?
The successor to the old bridge will consist of two substructures. And the new structure will be wider: there will be three lanes in each direction of travel - the continuous right-hand lane will not only serve as an acceleration and deceleration lane, but also as an intersection lane for local traffic.
