Railway flyover „Hürlistein“

Principal surveys during construction

Back

At the “Hürlistein” railway intersection near Kloten/Switzerland, the two-track lines from Wallisellen and Zürich Airport merge into a three-track line towards Effretikon. The level crossing of the tracks leads to conflicts in route scheduling and thus to a capacity bottleneck. The construction of a new, 400 m long flyover allows trains from Wallisellen to cross the Airport tracks without conflict. On both sides of the central bridge element, a 500 m long and a 1500 m long ramp are constructed respectively.
