The completion ends a project begun in 2010 for client, the Aarau district in the Canton of Aargau.

Its design for the latest bridge on a spot that has been a river crossing since Roman times projects simple solidity out of respect for the stone buildings of Aarau’s medieval old town.

The arches’ footings rest on two submerged caissons left from the former concrete bridge built in 1949, which replaced one built in 1848
