The 11.5 kilometer long Western Bypass serves as a ring road for Rosenheim to relieve the city center of long-distance traffic. The heart of the bypass are the bridges over the Mangfall, the Mangfall Canal, the Aicherpark industrial area and the Holzkirchen-Rosenheim railway line.
The approximately 670-meter-long bridge is constructed in two partial structures, with one section designed as a cable-stayed bridge.
The bridge structure consists of two substructures. The southern construction part 1 is a cable-stayed bridge, designed as a steel-concrete composite structure with a length of over 190 meters. The four pylons exceed the surrounding area by 16 meters.
The northern construction part 2 is designed as an elevated composite bridge, from which two ramp structures lead to the traffic level below.
The construction part 1 was erected using cantilever method from both riverbanks.
