According to Mordor Intelligence, the United States transportation infrastructure construction market size is expected to grow from USD 233.03 billion in 2025 to USD 242.8 billion in 2026 and is forecast to reach USD 298.12 billion by 2031 at 4.19% CAGR over 2026-2031.

This report is Segmented by Type (Roadways, Railways, Airways and Ports and Inland Waterways), by Construction Type (New Construction and Renovation), by Investment Source (Public and Private) and by States (Texas, California, Florida, New York, Illinois and Rest of US). The Report Offers Market Size and Forecasts in Value (USD) for all the Above Segments.
The USD 66 billion rail allocation embedded in the IIJA is triggering a wave of projects aimed at capacity, safety, and passenger-service improvements. Since January 2025, the Railroad Crossing Elimination Grant Program has awarded USD 1.1 billion across 123 projects, removing chokepoints that slow both freight and passenger services. Amtrak's goal of 64 million riders by 2040, up from 33 million pre-pandemic, is sharpening the focus on double-tracking, signaling upgrades, and station overhauls. Private rail operators are complementing federal outlays; Norfolk Southern's USD 200 million freight-corridor upgrade in Alabama exemplifies this synergy.
E-commerce sales volumes are heightening the need for freight-terminal capacity, short-haul rail spurs, and last-mile delivery depots. Colorado's 2024 Freight Plan cites rising parcel traffic as a catalyst for intermodal yard redesigns. Warehouse construction costs climbed 38% between 2020 and 2023 before stabilizing in 2024, underscoring the capital intensity of logistics real estate. Containerized freight movements reached record highs in 2024, further stretching terminal throughput.
The Congressional Research Service projects a USD 40 billion annual shortfall in the Highway Trust Fund by decade-end if current outflows persist. Rural counties often lack fiscal headroom to supply matching dollars, delaying bridge reconstructions, road widenings, and rural transit hubs. Proposed cuts in the House continuing-resolution draft would remove USD 2 billion earmarked for local safety projects, aggravating already thin capital pipelines.

The roadways segment kept its lead in 2025, accounting for 54.60% of total spending. Highways remain the backbone of U.S. mobility, and investors took notice: contract awards for highways and bridges hit a record USD 121 billion in 2024. Federal backing is equally strong. The Infrastructure Investment and Jobs Act set aside about USD 350 billion for highway programs through 2026, while the Biden-Harris Administration sent USD 62 billion to states for FY 2025, USD 18.8 billion more than in FY 2021. Industry leaders such as Bechtel, AECOM, and Skanska are vying for new interstate widenings and bridge replacements that upgrade aging assets.
Railways are growing fastest, with a 5.18% CAGR projected for 2026-2031. A USD 66 billion federal infusion under the IIJA is the main catalyst. In January 2025, the Federal Railroad Administration awarded USD 1.1 billion across 123 projects to remove grade crossings and improve safety. The airways segment benefits from an annual USD 1 billion Airport Terminal Program that funds terminal upgrades. Ports and inland waterways receive another USD 450 million through the FY 2025 Port Infrastructure Development Program. Better links among these modes are now essential: Colorado's 2024 Freight Plan highlights intermodal projects that align highways, rail spurs, and distribution hubs to meet e-commerce demand freight.colorado.gov.
