In July 2018, the new bowstring bridge at Herentals-Lier was placed above the Albert Canal on a temporary site. Its placing made it possible to demolish the existing bridge and build new abutments without interrupting the crossing of the canal. The abutments are now completed, the bridge will be moved by kamags to its final position this Saturday, August 10.
Bridge movement maneuvers represent the most spectacular part of operations. To attend, go this Saturday from 22h on the right bank downstream of the site. The various phases of the implementation will continue until Sunday, August 11th.
This bridge is part of the replacement of seven bridges, for a global project to size 9000 tons of the canal. The greisch office has been entrusted with the study of the superstructure, from the offer phase to the execution studies, through an optimization phase with reduction of quantities and simplification of structural details.
The whole comes from a DBFM (PPP) contract concluded by De Vlaamse Waterweg – the Flemish Inland Waterways Administration, with the consortium via T Albert (Franki Construct, Kumpen, Aswebo, Hye and Aelterman).
The 7 new bowstring bridges, based on a generic bridge concept with inclined arches joining in the middle, allow to release a draft of more than 9.1 m over a width of about 90 m. These bridges have a range of 123 m or 128 m for a working width of 16 m to 16.5 m. Each of them has 2 lanes and 2 sidewalks with bike lanes.
