Requirement

The Thorley Lane replacement bridge, crossing the M56 was assembled in an area approximately 200m from its final position and adjacent to the live carriageway. Upon completion, the bridge was transported and installed into its final position during a  weekend road closure. This approach minimised rush hour closures to the busy motorway which serves Manchester Airport.

The completed bridge consisted of four lines of girders approximately 90m long, 10m wide and 3m deep at the central section. The bridge was constructed from weathering grade steel to minimise future maintenance. It was fully assembled on temporary supports allowing the reinforced concrete deck and parapets to be completed before the bridge was jacked up and installed into its final position.
