Highway to Nothing: A scientific study conducted by local wildlife groups & academics has found that the Newbury bypass nine mile length of road has barely leaked any heavy metals on to surrounding land or into river courses. Thus, protecting the local biodiversity. This is because an installed network of "balancing ponds" which are water traps & filtration systems have worked as planned. This is the only road in Britain to be so well protected. Which in turn asks the question, why doesn't every stretch of new road have a system like this?
