Due to renovation work on the structure of the Fuhsebrücke bridge, the K57 between Nienhagen and Altencelle/Burg will be closed from Monday 18 September 2023 until further notice. Direct journeys on route 600 to the Burgstraße school centre will be diverted via the B3. The "Nienhagen, Bahnhofstraße" stop cannot be served; an alternative stop is available on both sides of Dorfstraße, near the bakery.
