The K5508 is an important connceting road beetween Hopfau und Glatt (Black Forest-Germany). It is very awkward to detour the road. Due to the need for rehabilitation, the road had to be closed. Industry and hotel industry are dependent on the connceting road and feared high losses. By using the NovoCrete-Technology, the construction time could be shortened by 6 months, so that the residents could use the familiar infrastructur quickly again.
