A key milestone in the Ordsall Chord project has been reached with the lifting into place of two arches for the ‘network arch bridge’ crossing the river Irwell.
The 600-tonne bridge support has been designed by architect BDP and manufactured by Severfield. Individual sections have been welded together at the site and were lifted into place as one piece via a tandem crane lift. The design uses inclined hangers which cross each other at least twice instead of vertical hangers, which Network Rail says allows for a more elegant design that is thinner and uses less material.
The Ordsall Chord is a 340-metre connecting viaduct which will link Manchester’s Piccadilly, Oxford Road and Victoria stations, enabling new direct services to run through to Manchester Airport. It is due to open for passenger services in December 2017. Network Rail has formed an alliance with contractors Amey, Skanska, Bam Nuttall and Siemens to construct the chord.
