Ny jernbanebru ved Pegnitz

The project 'Eisenbahnüberführung Artelshofen und Steinbruch' involves the construction of a replacement railway bridge near Artelshofen at railway kilometer 40.910 and between Enzendorf and Rupprechtstegen over the Pegnitz at railway kilometer 43.489. This includes a gradient adjustment. The construction is carried out in two main phases: the installation of temporary bridges in 2019 and the insertion of the new superstructure in 2020. During the break periods, the substructures are created.

Detaljert byggeservices inkludert

The detailed construction services include earthworks, the dismantling of the existing structures, the creation of shoring and deep foundations, the installation of temporary bridges, track construction including gradient adjustments, and the erection of the substructures with steel superstructures utilizing railway cranes. Additional works involve caps, natural stone cladding of the substructures, street construction, and the lateral displacement and lowering of the new superstructures. Environmental considerations, particularly concerning water protection, play a significant role in the project.

Prosjektkostnad og tidsplan

The total cost of the project is estimated at 6.1 million CHF, 5.5 million EUR, 4.8 million GBP, 55.5 million NOK, 56.9 million SEK, and 6.4 million USD, based on the average annual exchange rates during the project implementation period. Construction began in November 2018, with completion initially planned in March 2021. The construction posed several challenges, including working under live tracks with tight spatial constraints and inner-city conditions, as well as the overheight manufacture of the superstructure with lateral displacement and lowering, winter construction, and work during restricted periods.
