# List of road projects in the UK

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. 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.
