– could the viaduct be put back into operation in its old form. The reconstruction of the viaduct took into account the historical shape of the bridge, such that since 1950 it has resembled its old form once again. However, the keystones of the viaduct could not be reinstated. In July 2009, after being displayed for many years as a monument in Adenauerstraße, Altenbeken, they were integrated into the viaduct's newly constructed viewing platform. Viaduktfest Between 11 and 21 July 2003, under the name "Vivat Viaduct", Altenbeken celebrated the 150th anniversary of the viaduct. About 40,000 visitors came to Altenbeken. As the festival was so successful, it was decided to organise it again every two years as a "town and station festival". Thus, in 2005, 2007, 2009 and 2011, many people came to the event. The Viaduktfest also includes a viaduct walk through the town and a plastic duck race on the Beke river. Celebrities such as Urban Priol, Hennes Bender, Götz Alsmann, Ingo Oschmann or Guildo Horn have complemented the Viaduktfeste with cultural events. The festival always takes place in early July of odd numbered years.
