Combined solution: the structures of the A120 Little Hadham bypass and flood alleviation scheme

Abstract

<p>The village of Little Hadham in the UK has suffered from heavy traffic, air pollution and flooding over many years. The village also creates a major bottleneck to traffic flows on the main A120 road through the region, a major east west route crucial for the prosperity of the East of England.</p><p>These multiple issues are being resolved though the construction of a combined bypass and flood alleviation scheme. By combining the resources and requirements of the highway and environmental authorities the scheme provides a sustainable and cost-effective solution to these issues with highway embankments and bridges also acting as flood alleviation dams and spillway structures. These combined benefits ensured the commercial viability of the scheme.</p><p>This paper gives an overview of the structures and design challenges faced and how the requirements of the two functions have been combined into a single solution that ensures the future of Little Hadham and promotes growth in the region as a whole.</p>
