All the minor roads in the entire UK were totaled around 347114 kilometers. So, the total length of all major and minor roads in the UK in 2020 was 398359 kilometers. The growth rate of the length of the major roads from 2010 to 2020 was about 0.18% annually. The growth rate of minor roads from 2010 to 2020 was about 0.09% annually.

The maintenance cost expenditure for type ‘A’ roads were about £685 million for structural purposes and £275 million for routine and other tasks. The total highway maintenance cost was £960 million for type A roads in the year 2019. Another £2569 million were spent for the development of structure of the local authority roads and £1027 million were spent for the routine and other task of development. Around £3920 million pounds were spent on the local authority roads in 2019. This spending amount is going to increase as time progress. But due to a pandemic the spending on the road is going to be reduced and after full recovery from the pandemic this spending will continue to rise. Yearly, about 3% of the principal type A road required maintenance and on average 6% of the non-principal roads requires maintenance. In 2021 the local highway maintenance needs £725 million for element funding.
