A temporary diversion of pedestrian and cycling routes needed to be created in order for general maintenance to be carried out on the inner and outer sections of the Ludwigsbrücke bridge close to Deutsches Museum in Munich. To this end, between March 22 and 29 six temporary bridges were transported, assembled and successfully lifted into position in individual sections in night shifts. The temporary bridges weigh over 60 tons and measure around 50 meters in length, which meant two high-performance mobile cranes with lifting capacities of up to 450 tons were required to lift them. To ensure barrier-free use of the pedestrian and cycling routes during the maintenance period, flat, sloping access ramps are currently being manufactured.
This paves the way for the extensive main construction measures planned for maintenance of the Ludwigsbrücke from May 2020. The aim here is to preserve for as long as possible the two sections of the bridge, which were built from 1934 to 1935, in this historically significant location where the first crossing over the River Isar was erected in the 12th century – the beginnings of the foundation of the city of Munich. After the maintenance work is completed in 2022, the temporary bridges will be dismantled, and the Ludwigsbrücke bridges will then be back in use for all traffic as one of the most important crossings over the Isar.
WTM Engineers has been supervising this project with extensive services since 2009. These include reporting on the state of the structure, follow-up computations and categorization calculations, as well as planning and overseeing the maintenance work with the traffic phases, the six temporary bridges, laying of the different sections during the work, and a cathodic corrosion protection system (CCP).
WTM Engineers begleitet dieses Projekt seit 2009 mit umfangreichen Leistungen. Dazu zählen u.a. Gutachten zum Bauwerkszustand, Nachrechnungen und Einstufungsberechnungen sowie aktuell die Planung und Überwachung der Instandsetzung mit den Verkehrsphasen, den sechs Behelfsbrücken, bauzeitlicher Verlegung der Sparten und einem kathodischen Korrosionsschutz-System (KKS).
