Road to the future: A421, UK

By thinking differently, we are constructing a road near Bedford in England more sustainably than ever before. We are using alternative materials − some previously unheard of in highway construction and aiming for major CO2 savings. And this road is just the beginning of a long journey: we are sharing the ideas pioneered here across the Group.

"Great teamwork by great people with great ideas have combined to deliver a sustainable A421. Our legacy will be a safer road for sustainable communities."

"The A421 sets a benchmark for the use of alternative materials on future projects. The use of tyres and power station ash are a win-win, environmentally and economically."
