Oktober 2009 – A double-tube tunnel with a length of 1080 m per tube. Two service buildings, each with a MV system with 630 kVA transformers and a 60 kVA UPS system to ensure an uninterrupted power supply to safety components.
After more than 30 years in the planning and three years in the building, the new stretch of the B14, the Winnenden bypass, has finally been completed.
