BRIDGING THE NORTHUMBERLAND GAP

This article describes the North Seaton bridge which crosses the River Wansbeck Valley at a skew of approximately 25 degrees and links north and south Northumberland. This six- span prestressed concrete viaduct, 180M long and 12,4M wide, carries the newly constructed south east Northumberland spine road across the river. The in-situ, post-tensioned structure consists of twin T-Beams. Each T-Beam has its own independent line of support columns, and each pair of columns is skewed to line up with the flow of the tide. Bank seats support the ends of the deck, which is hinged at the south end and has an expansion joint at the north end. Details are given of the deck formwork used, casting of the concrete and bbrv system of prestressing. The bridge deck is supported on five piers each comprising two reinforced concrete columns. The piers except no. 1 pier stand on A concrete columns. The piers except No. 1 pier stand on a 14 h section steel piles driven to a depth of 15 M in the underlying rock. All five foundations are set skew to the line of the bridge and are buried to reduce scour and obstruction of the river bed. Data are also presented on the construction of the abutments and costs. /TRRL/
