New U-railway line in the center of Dortmund will replace the existing overground running tram.

The Silberberg railway tunnel in the Thuringian Forest is part of the new Ebensfeld – Erfurt railway line. The new line connects the old and the new federal states.

The Henndorf bypass lead to a noticeable relief of traffic congestion. Centrepiece of the bypass is the double lane 2,150 meters long road tunnel, which is now used by approx. 20,000 vehicles per day.
