The new Swale Crossing

The erection of 10,000 t of bridge steelwork at the new Swale Crossing in Kent included one of the UK's longest launch cantilevers at 92.5m. The new road bridge is part of the A249 Iwade Bypass to Queenborough Improvement Scheme between the Isle of Sheppey and mainland Kent. It will carry a fully dualled link from the M2 at Stockbury to Sheerness. The project is a design build finance and operate contract, awarded to Sheppey Route Ltd., a company established by Carillion Private Finance. Cass Hayward was appointed as bridge designer. The viaduct will provide clearance of 29m above high water level. The crossing will consist of two abutments, 18 pier bases, 36 supported columns and 1.27km of bridge deck. The bridge will consist of four plate girders with cross girders below the deck slab. The 19 spans will vary in length from 444m to 92.5m. The main piers each side of the longest central navigation span were founded directly on London Clay and were constructed with a permanent steel sheet piled cofferdam. The five-phase steelwork erection sequence is described.
