Removal of the Overeindes Bridge, Amsterdam-Rijn Canal, The Netherlands
ALE has successfully completed the removal of the Overeindse Bridge. This was part of the overall bridge exchange project and the client completed the installation scope of the project.
The bridge was built on the yard of Mercon in Gorinchem, The Netherlands, and was split into four phases.
Load-out of 550t, 120m long arch bridge onto 66m x 15m barge using 24 axle lines of SPMT.
Removal of the arch of the bridge and transportation of the bridge deck and arch to the assembly location. Once at the location the arch was assembled back onto the bridge.
The bridge deck was transported on four connected barges with a total length of 171m, whilst the arch of the bridge was transported on an inland vessel.
The total voyage was approximately 75km over inland waters to Nieuwegein.
Removal of the old Overeindse Bridge and installation of the new Overeindse Bridge.
During a period of eight hours the Amsterdam-Rijn canal was closed for the inland navigation. ALE successfully completed the removal of the old bridge ahead of schedule, in just over three hours, allowing the client more time for the installation of the new bridge.
In order to position the barge with the jacking system, ALE utilised four winches and two tugs.
To transfer the total weight onto the barge the Mega Jack 800 system was used in combination with 1,000 Cu M/Hr ballasting capacity.
The old bridge was jacked-down onto the supports of the demobilser (805t). ALE utilised the Mega Jack 800 system and the operation was completed in less than six hours.
