Network Rail job completed without affecting services

May Gurney used what is reputed to be the world’s most powerful mobile crane to spectacularly lift a new footbridge into place over the East Coast Main Line at Durham – without disturbing a single rail journey.

With the bridge spanning a cutting next to a housing estate and a nature reserve, the task of removing the old bridge and getting the new one in posed challenge for the project team.

The new structure has been installed with GRP parapets and deck panels to reduce weight as much as possible. The existing concrete abutments were found to be in good condition, allowing them to be used for the new structure.

The old bridge was removed and the new one put into place overnight on 27/28 March. An onsite trial lift of the new footbridge during the dayshift confirmed the crane capability at the required radius and also enabled the public to view the crane in operation, which generated considerable local interest.

Warrick Dent, area general manager for Network Rail, said: “We have a commitment to our passengers to complete improvement works with the minimum possible disturbance to their journey.

“In this case that was a challenge because of the short amount of time between trains and because the nearest place to site the crane is more than 85 metres from the bridge.

“Our engineers have come up with a creative and cost effective solution which has replaced the bridge and kept trains running throughout and I would like to congratulate them on a job well done.”

Footnote: The work was carried out by May Gurney on behalf of Network Rail under a contract to replace, restore and maintain the UK’s rail network structures, which runs until 2012.
