The Fly-Over ramp – as a "bridge over the bridge" – used for uninterrupted replacements of expansion joints and for implementing repairs has garnered an excellent reputation since 1999 at various locations. Many roadway expansion structures installed in the past decades are currently greatly damaged by mechanical effects. It is therefore necessary to replace the damaged mechanical structures with finger expansion sections. Because repairs and the related closure of individual lanes lead to enormous diversions and huge traffic jams, the idea of using a ramp was born. The engineers at Waagner-Biro took on the challenge and developed the Fly-Over ramp which was used for the first time in 1999 on the south-east tangent. The necessary width can be achieved by arranging individual elements in parallel. The Fly-Over ramp can therefore be extended indefinitely.
