Highways & Tunnels Infrastructure Projects in USA (2026)

Highways and tunnels form the backbone of American mobility, accommodating billions of annual passenger miles and serving as critical conduits for national supply chain logistics. Under the Bipartisan Infrastructure Law (IIJA) and Federal Highway Administration (FHWA) capital grant programs, state transportation departments across the nation are executing multi-billion dollar corridor modernizations, pavement line rebuilds, and sub-surface tunnel construction.

Major active projects in this sector focus on resolving severe freight bottlenecks, expanding bottlenecked suburban lanes with dynamic express tolling, and constructing resilient sub-river transit tunnels. Featured initiatives include the $16B+ Hudson Tunnel Project in New York and New Jersey, the multi-state I-80 Reconstruction, and major Texas Department of Transportation (TxDOT) expansions along the Interstate 35 corridor.
