road infrastructure
Paved travel networks
Road infrastructure is the system of physical structures supporting vehicle travel—roads, highways, bridges, tunnels, traffic signals, and signage.
The term appears in policy discussions about maintenance, funding, and modernization: The bill allocates billions for crumbling road infrastructure.
Infrastructure implies the underlying framework that enables activity, so road infrastructure emphasizes the foundational nature of these systems rather than the surfaces themselves.
