| Abstract: |
Special methods had to be developed for the deconstruction of two bridges in the course of the widening of the motorway A7 in Hamburg. At one bridge blocks of ultra high strength concrete with steel fibres are used as temporary anchoring of the prestress tendons. At the other bridge the old concrete superstructure is removed by a special incremental launching backwards. |
