Project Description: The Frankfurter Kreuz (173 million Euros/ 189 million USD) and about a 6 year project with four quadrants of the clover leaf. During the construction of this project no traffic could be impeded or blocked at any time which lead this to be a very changeling engineering project.
General: The new central building (four smaller independent bridges) spans the A5 autobahn, a total length of over 100m / 328ft with four fields with a total width of almost 80m / 262ft. There are four additional bridges which are in the clover leafs, these are all in curves and are road / traffic in type. Each of the clovers leaf bridges an additional temporary bridge was made so four bridges were made in parallel to those permanent ones.
