The share of motorways in the total road network in the US is projected to remain constant at 1.16% from 2024 through 2028. This follows a stable trend observed in recent years, with no change in the share noted since 2023. As this percentage remains unchanged, the year-on-year variation is zero, indicating a flat growth pattern. Over the next five years, the Compound Annual Growth Rate (CAGR) also suggests no increase in motorway share within the overall road network.

Future trends to watch for:

Infrastructure investments or policy changes that could alter motorway expansion.
Technological advancements in transportation that may impact road network compositions.
Potential environmental regulations influencing road construction and maintenance priorities.
