The common goal is to upgrade the Isar bridges to the current standard with increased load-bearing capacities. The two bridges over the Kleine and Große Isar will be replaced by two new structures. Temporary bridges will be used so that traffic can continue to flow during the construction period. In addition, the new bridge structures will each be equipped with a 4-metre-wide footpath and cycle path.
The project is due to be completed by June 2027.
