Overview

Transportation Infrastructure covers the physical assets and operations that move people and goods — airports, seaports, toll roads, bridges and tunnels, rail and transit infrastructure, and parking. Sized from private operations and support activities, it represents roughly $84 billion, though the assets themselves are largely publicly owned by authorities and agencies outside this figure.

The defining trend is the growing role of private capital — infrastructure funds, concessionaires, and public-private partnerships (P3s) increasingly own, operate, and finance these long-life, recurring-revenue assets. Demand is driven by trade and travel recovery, federal infrastructure funding (the IIJA), and the privatization/concession model, making transportation infrastructure a prized, actively-invested category; transportation services are profiled under Transportation & Logistics.

Market snapshot

Market size: ~$56B
Growth: ~5.3%CAGR (2017–22, nominal)
Companies: ~8,229 firms

Firms by employee count

79.6% of firms have fewer than 20 employees: 6,546 micro-businesses, below most mandates.

The investable universe1,677 firms with 20+ employees

20–99: 99059%
100–499: 37422%
500+: 31319%

Percentages are of the 20+ employee universe. 20–99 and 100–499 are the lower-middle market; 500+ is at scale.

What is measured here is the operating layer — the companies that run terminals, gates, berths and lots — not the assets themselves, which are overwhelmingly public. That distinction is the investable insight: concessions and operating contracts change hands frequently and at infrastructure multiples, while the underlying asset never trades at all.

Geographic concentration

Alaska, Louisiana and New York lead — three different kinds of dependence. Alaska runs on air and marine links because roads do not reach most of it, Louisiana on the Mississippi and its port complex, and New York on the densest transit and parking market in the country.
