List of road projects in the UK

The Inverness Trunk Road Link West Section under construction in January 2020

This article lists current and planned road building in the United Kingdom. Significant investment is expected, including plans for £14 billion of investment in road expansion by England's National Highways. ^[1] In addition to physical expansion, smart motorways have been pursued as a means to increase capacity by introducing regular traffic on the hard shoulder. Transport is devolved, projects in Scotland, Wales, and Northern Ireland are delivered in co-operation with the devolved authorities of Transport Scotland, the Welsh Government, and DfI Roads respectively.
