Exam Summer 2014
As the old Hergiswald Bridge by Jospeh Ritter from 1791 no longer met the latest requirements, the municipality of Kriens planned a bypass to the north of the old bridge, and in 2009, called for a competition to design a new bridge. The new bridge, designed by a team of civil engineers around Fuerst Laffranchi together with Ilg Santer Architects, relates in form and materialization to the adjacent historic bridge. The bridge beam with a bottom chord in tension is a reflection of the compression arch of the old bridge. The key structural elements of the new bridge are kept in timber as in the historic bridge.
