In Hesse, a multi-span bridge, built in 1971, was renovated and repaired. In this project, carbon reinforced concrete was used for the first time to reinforce a motorway bridge. The approximately 70 m long structure in Frankfurt transfers the A648 motorway in three parts over two cycle paths and the the Nidda river. As part of the renovation, the bridge's deficit in load-bearing capacity was compensated for by targeted reinforcement with just a few centimeters of carbon reinforced concrete. At the top, the reinforcement layer was completely integrated into the road structure without having to raise the gradient. The restrictions for the underpassing cycle paths in the peripheral areas are minimal with only 3.5 cm reinforcement layer thickness. The sensitive nature around the river Nidda under the main field remained completely untouched by the construction work.
