Replacement of bridge B470 Auerbach in der Oberpfalz
Short description
Two existing ridges on the B470 are being completely renewed.
The project
The two existing bridges from the 1970s on the B470 over the 3rd and 4th field paths near Auerbach in der Oberpfalz are being completely renewed due to clear signs of wear and tear and limitations in terms of durability and road safety.
A temporary bypass will initially be set up to ensure traffic can continue during the construction period. The old bridge structures will then be dismantled. The new bridge will be built as a single-span bridge structure made of reinforced concrete using an integral frame construction method. This construction method guarantees a robust structure with a long service life and low maintenance requirements. In addition, road, earthworks and drainage work will be carried out as well as the construction of the bridge equipment.
