Sunderland City Council
The three-span cable-stayed bridge construction comprised piled foundations, reinforced concrete sub-structure, a steel concrete composite bridge deck with precast concrete decking and steel A frame pylon.
The two main cable-stayed spans are 148m each with a third fixed span of 40m on the northern side. In order to construct the permanent works, temporary works e.g. a cofferdam, was utilised to aid construction, to reduce risks and impact of the works, and to reduce the works programme.
In addition to the construction of a new river bridge the project included the construction of 2.8km of new carriageway and is forecast to carry 27,000 vehicles per day. Additional highway works included: 750m of new single lane carriageway, new traffic signals, road realignments, a Metro line crossing and a new access with cofferdam piling duties and the installation of the bridge decking.
