Prague Negrelli viaduct modernisation enters next phase

The reconstruction of the Negrelli Viaduct in Prague will enter its next stage, with the removal of the steel bridge over the Prvního Pluku Street and its replacement by a new reinforced concrete structure with steel beams. The bridge over Prvního Pluku Street was built in 1936, but its bottom structure is an original one going back to 1872. The bridge does not meet anymore the current rail technical, operational and noise parameters.
The 1130 metre Negrelli Viaduct is the second oldest bridge in Prague and the oldest railway bridge across the Vltava River, being built in 1850. The reconstruction project will allow trains to run faster, increase the capacity of the railway track and adjust the track to current noise and vibration limits. The contractor of the reconstruction project is a consortium of Hochtief CZ, Strabag Rail and Avers companies.
