U4 Extension to Horner Geest - Replacement Planting, Landscaping, Green Spaces and Parking Areas in Section 2 [ba]

Hamburger Hochbahn is currently building the extension of the U-Bahn line U4 to the east, connecting the Horn district to the U-Bahn network. In a first construction phase, the Horner Rennbahn station, among other things, has already been expanded and completed. The replacement planting and landscaping work has already been carried out here. In the second construction phase, the new U4 line with the Stoltenstraße and Horner Geest stations will be built, which is scheduled to go into operation in December 2027. The second construction phase begins east of Hermannstal street and follows Manshardtstraße to the east up to Silberberg street. The U-Bahn tunnel was built using the cut-and-cover method and runs for the most part under Manshardtstraße, which is currently being restored. The length of this section of Manshardtstraße is approx. 1.6 km. Areas on both sides of Manshardtstraße must be restored along the entire length. For movement and construction site setup areas, private areas, public green spaces, and schoolyard areas were cleared and used laterally to the construction pit. These areas must also be restored. The larger construction site setup areas to be restored (soil storage, concrete plant, and water treatment plant) are located at Horner Rennbahn.
