Seidewitztal Bridge A17

Germany

With an arch span of 154 m, the Seidewitztal Bridge is the biggest reinforced-concrete arched bridge in Saxony. Using Large-area formwork Top 50 combined with Climbing formwork MF240 enabled its piers to be constructed simply, safely and quickly. The arch and the bridge superstructure were also formed using Doka systems (Top 50 and composite forming carriages).
