Osprey Heavy Lift were contracted to carry out the bridge replacement work on two single span under bridges on the busy Manchester City Centre to Manchester Airport rail line.
The urban location of the Fog Lane and Mauldeth Road bridges required engagement and collaboration between Network Rail, the local authorities and the local communities to arrive at an installation solution accepted by all.
Lead up preparation, possessions and track access were extremely limited on this busy line meaning elective planning and management of all works was essential to the success of the project.
The two bridge replacements were carried out concurrently within a 51-hour core possession. The work involved the demolition and removal of the existing bridge structures to the underside of existing pad-stones and the installation of new bridge superstructures reusing the existing masonry abutments.
In the lead up preparation, calculating the optimum position of the SPMTs for increased stability allowed the introduction of a maximum width into the bridge design, with the design being developed to future proof the bridge and nearby platforms.
The structural elements of both bridges were then prefabricated offsite and transported to the site compound located close to the existing bridge, where they were then constructed on trestles.
Redundant and new bridges were driven out and in using our SPMTs within a localised road closure to ensure minimal disruption to rail users and the local community.
Osprey’s Heavy Lift team took the project from enquiry to successful completion by providing a solution focused approach, using in house assets and skills to ensure that the project was delivered safely, on time, within budget and in a value-added manner.
