Main contractor for the job is John Sisk & Son, working for Ballymore Properties.
The Leamouth North Bridge spans the River Lea between Canning Town station and Ballymore’s new London Island development in the Docklands. The bridge will connect the development site, currently in the construction phase by Ballymore, to Canning Town and provide access for pedestrians and cyclists to pass between them.
The bridge weighs 160 tonnes and was lifted into place on 5th August by a 1200-tonne capacity lattice boom crawler crane. Because the bridge is asymmetrical, the positioning of the lifting points was critical to ensure that the bridge was correctly trimmed during lifting.
The 80-metre span steel bridge was fabricated in Carlow by Thompsons. Sisk’s design consultant is O’Connor Sutton Cronin & Associates.
The concept design, by structural engineers Davies Maguire & Whitby, allows the bridge to open vertically to let boats under it. The next phase of the works involves installation of the hydraulics and control systems.
