Transport in the United Kingdom is facilitated by road, rail, air and water networks. Some aspects of transport are a devolved matter, with each of the countries of the United Kingdom having separate systems under separate governments.
A radial road network totals 29,145 miles (46,904 km) of main roads, 2,173 miles (3,497 km) of motorways and 213,750 miles (344,000 km) of paved roads. The National Rail network of 10,072 route miles (16,116 km) in Great Britain and 189 route miles (303 route km) in Northern Ireland carries over 18,000 passenger and 1,000 freight trains daily.
Urban rail networks exist in all cities and towns with dense bus and light rail networks. There are many regional and international airports, with Heathrow Airport in London being the second busiest in the world and busiest in Europe. UK ports handled 486 million tons of goods in 2019.
