Fog Lane and Mauldeth Road Bridge Reconstructions

Project Outline

The two single span underbridges on the very busy Manchester city centre to Manchester Airport line were replaced with new u-type steel decks on reinforced concrete cill beams.

Key Challenges

The bridges' urban location 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 effective planning and management of all works were essential to the success of the project.

Early engagement and positive collaboration with local businesses was essential to manage the potential risks of the pedestrian interface on the self propelled mobile transporter (SPMT) travel routes during core possession.

Project Delivery and Innovations

The two bridge replacements were carried out concurrently within a 51-hour core possession in March 2017. 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 re-using the existing masonry abutments.

The bridges' structural elements were prefabricated off-site then transported to the site compound located close to the existing bridge where they were constructed on trestles. Redundant and new bridges were driven out and in using an SPMT within a localised road closure to ensure minimal disruption to rail users and the local community. 

Innovations included accommodating maximised width into the bridge design, with the design being developed to future-proof the bridge and nearby platforms.
