Roads, roads, roads

If there’s one issue to excite folk, then that’s the issue of ‘roads’ – whether it’s potholes or bypasses or new roads.

The problem is that new roads generally mean more traffic which means more pollution – as well as greater expense through our taxes! “Do we even want roads?” – Vision Group for Sidmouth

In another corner of the county, an experiment is happening:

A Devon road is to become the UK’s first “carbon negative” highway after the government named it as one in just seven in the country to receive cash towards that objective.

The A382 link road development near Newton Abbot is getting £3.7 million to decarbonise the construction and maintenance of the road. It’s from a programme called Live Labs 2, funded by the Department for Transport (DfT) and organised by ADEPT (Association of Directors of Environment, Economy, Planning & Transport).

… working with the University of Exeter and maintenance contractor Milestone Infrastructure to develop a “carbon calculator” to identify and measure the carbon produced in every aspect of road repairs and construction. Potential carbon saving measures proposed for the project include using local recycled materials, ensuring construction plant and equipment is sustainable, installing streetlighting that can generate power, and establishing low maintenance verges and hedgerows.

Dr Dan Lash, from the University of Exeter, said: We have been working with Devon County Council for some time on assessing the climate change impact of its road projects. This has involved producing innovative tools, and standards that are in the process of being incorporated into national guidance for the sector.”

But the scheme is very much part of the wider search for ‘sustainable construction’ in the county: The Built Environment – Devon Climate Emergency

With Dr Lash of the University of Exeter very much on board – and very much part of the research: Centre for Energy and the Environment | Centre for Energy and the Environment | University of Exeter
