The share of urban roads in the UK's total road network is forecasted to slightly increase from 37.01% in 2024 to 37.24% in 2028. This gradual rise reflects a modest compound annual growth rate (CAGR) over the five-year forecast period. As of 2023, the proportion was slightly under 37%, indicating an ongoing trend towards an expanding urban road network relative to total roads.

Future trends to watch include:

Increasing urbanization may further elevate the share of urban roads, driven by population growth in cities.
Government infrastructure investments could influence the rate of urban road expansion.
Technological advancement in transportation might shift focus from expanding road networks to optimized traffic management.
