Overview

Heavy & Highway Construction covers heavy civil contractors building highways, streets, bridges, and other large infrastructure. At ~$194B it is a capital- and equipment-intensive, bonding-heavy segment serving largely public-sector clients (DOTs, municipalities), led by large civil contractors alongside regional players.

Demand is driven by public infrastructure spending — federal surface-transportation and infrastructure funding being a major multi-year tailwind. The work requires heavy equipment, aggregates access, and bonding capacity, creating scale barriers, though the segment remains fragmented regionally.
