A tunnel made of glass

With the complete extension of the partially glazed noise control enclosure, a bottleneck on the A1 federal motorway was eased. Therefore, the road section between the German railway construction and the interchange Köln-West up to the junction Köln-Lövenich has become an attractive north-south connection for road users. The whole project was equipped with new state-of-the-art safety equipment. After a trial period of about five years, the tunnel was finally officially opened for the directional traffic in December 2012.
