At 40,000 vehicles per day, the 50 year old Ackermann Bridge that crosses the Wertach River in Augsburg, Germany is one of the most heavily travelled bridges in the city. The structure was badly deteriorated and is therefore being replaced by a new bridge.
During construction of the new bridge, traffic is being diverted across a temporary bridge south of Ackermann Street.
The substructures of the temporary bridge were built using the sheet piling method. Approx. 5,000 m² of sheet piles were installed in two abutments and three pile structures for this purpose. The piles are up to 15 m long. The sheet pile structures are tied back using 80 t of walers consisting of double U steel and 35 t of tie rods.
