The narrow medieval bridge over the River Nene at Wansford (known as Wansford Bridge) was a great hindrance to the increasing traffic using the Great North Road (the later A1) in the 1920s. The A1 is the major route from London to Edinburgh.
The 1929 Bypass bridge
A new bridge was constructed between 1925 and 1928 to the east of the medieval bridge. The Consultant Architect was Maxwell Ayrton and Associate Engineer was Sir Owen Williams. It was a similar design to his Spey Bridge of the same period. The bridge had a main span of 110 feet and flood arch spans of 50 feet either side. It was built of mass concrete in order to conform with the old-world character of the local architecture.
The 1975 Bypass bridge
The 1929 bridge continued as a single carriageway bottleneck until 1975 when a second bridge was built to the east. This formed a new southbound carriageway and the 1929 bridge became the northbound carriageway.
