Details are given of the methods used to restore the three bridges whereby the A509 Newport Pagnell-Kettering road crosses the flood palin of the river Great Ouse. The bridges are a 5-span masonry arch bridge, a set of flood spans and a mill stream bridge. The weakness of the ancient masonry bridge derived from the decayed condition of the spandrel walls and the poor load-distribution characteristics of the arch filling. The widenings in the new work were designed as mass-concrete arches, construction keys being provided at the springings, at 2 intermediate positions on the end spans and at 4 intermediate positions on the three inner spans to provide articulation. The parapets of both the main bridge and the flood arches were constructed of reinforced concrete. The mill-stream bridge, having a span of 8M, was reconstructed using mass concrete abutments founded on steel h-piles and formed in front of the original brick and masonry abutment. /TRRL/
