Smart motorways and expressways: Over the coming years, a national spine of smart motorways will add more than 400 miles of extra capacity to our highways. And we’ll introduce a new standard for A roads, known as ‘expressways’: with modernised junctions, refuge areas and specialist technology to quickly detect incidents and get traffic moving again. Unblocking bottlenecks: We’ll tackle congestion hotspots across the country, ranging from improving the A14, to progressing plans for a new lower Thames crossing. Safer roads: Our roads are already some of the safest in the world. However, we’ll make them even safer by improving road design, while influencing driver behaviour and encouraging regular vehicle maintenance. Greener roads: We’ll play our part in the national effort to manage carbon emissions. We’ll tackle noise pollution, support specialist research and improve how we monitor air quality. We’ll create a network that is open to all, and boost facilities for people that cycle or walk along our routes.
