Final Peace Bridge deck sections moved into place

Work to install the final deck sections of the £8.6M Peace Bridge at Ebrington Waterfront, Londonderry, has been completed by Graham Construction.

The landmark fixed-span foot / cycle bridge unites the communities on the east and west banks of the River Foyle and is the first bridge of its type to be built in the UK. It comprises a curved self-anchored suspension bridge, with two inclined pylons dividing the structure into three continuous spans of 65, 100 and 65m over the river with two approach spans of 37m to cross the Derry to Castle Rock railway line and a proposed access road.

The process of hoisting the deck sections into place involved crossing the main Londonderry to Belfast railway line, meaning Graham Construction could only undertake the work during the night once trains had stopped running.

Each deck section weighed 75t and were lifted in with a maximum radius of 18m.

Graham Construction operations director Leo Martin said: “This was a challenging piece of engineering work, but lifting the deck sections into place represents a significant step forward in the delivery of this project.

“This project is providing jobs and investment for the construction industry and the Peace Bridge is set to become one of the most high profile public structures in the north west of Northern Ireland – meaning it’s vital we get it right.

“We look forward to completing this landmark project and it opening to the public later this year.”

The overall deck width of the Peace Bridge, including the cross girder, varies between 4m to 5.6m and parapets are a minimum 1.4m high and formed in stainless steel. The pylon comprises a varying six-sided fabricated steel section with an overall height of 32m. The deck is supported by 52mm diameter bar tendon hangers attached to a 120mm diameter locked coil strand suspension cables.

The deck is constructed with weathering steel which was painted white to meet the architect’s design.
