Renovating and enlarging a tunnel - that's what engineers plan again and again. "But with the Petersberg Tunnel on the Moselle route from Koblenz to Trier, they are setting standards," writes Prof. Dr.-Ing. Dietmar Mähner of the Institute for Underground Construction at Münster University of Applied Sciences.
Safety as a driver of innovation
Already in the bidding phase, Marti engineers developed various concepts to combine technology, innovation and safety. For the Petersberg Tunnel, they developed a tunnel widening system that offers protection against the dangers of excavation work. Additionally, a continuous protective enclosure with integrated overhead contact line was developed. This, too, is a novelty.
