Highway, street and bridge construction

This industry comprises establishments primarily engaged in the construction of highways (including elevated), streets, roads, airport runways, public sidewalks, or bridges. The work performed may include new work, reconstruction, rehabilitation, and repairs. Specialized trade activities related to highway, street, and bridge construction (e.g., installing guardrails on highways) are included. — Statistics Canada, NAICS 2022A

Size and shape

How many businesses there are and how small they are. Fragmentation is the first thing an entrant — or anyone selling software into this industry — needs to know, and it is one of the few things that is actually measured.

Largest four provinces by establishment count. Establishments with employees only — sole operators with no payroll are not in this table, so in trades and personal services the true number of businesses is higher.

Measured, not forecast: the share of US establishments opening in one year that were still active later. It counts good operators and bad ones together, which is exactly why it is the honest answer to “what are the odds”. It is for the whole sector rather than this market, and the ten-year figure comes from an older cohort because no younger one has reached ten years.

binding constraint: capital intensity

Roads are rebuilt whether or not the economy is growing, the owner is a government that pays, and the record at Utility System Construction already covers the prequalification-and-bonding gate that guards all public civil work. This group has a second, harder gate behind that one. Public paving is awarded to the lowest compliant bid, and the lowest bid belongs to whoever has the cheapest hot-mix asphalt delivered to the job — which means whoever owns the asphalt plant, the quarry feeding it and the liquid-asphalt supply nearest the road. The consolidators say so in their filings. Construction Partners describes its strategy as vertical integration across hot-mix plants, paving, aggregates and liquid asphalt; in fiscal 2025 it grew revenue 54% to US$2.81B, only 8.4% of it organic, by buying five companies that brought 27 asphalt plants, four aggregate facilities and an asphalt terminal [A]. In Ontario, Colas paid C$913M for Miller McAsphalt — about C$1.3B of revenue at a 7% operating margin — to get road crews and the national bitumen terminal network together [A]. An entrant with pavers and a bond but no plant buys its mix from the firm it is bidding against. The size bands fit: 38% of the 2,092 establishments have twenty or more employees, and the US average is 33 per establishment. The reachable fringe — driveways, parking lots, sidewalk work — is real but is private paving, not this market.

Who works here

The occupations employed in Construction, most concentrated in it first. The share is measured against the whole sector, not this industry — the published cross-tabulation stops there.

Concentrated in this sectorA

These jobs are mostly done here. An operator in this industry is competing for them against others in the same industry, not against the whole economy.

And the jobs every business has

Found across at least fourteen of the twenty sectors. In a small establishment several of these are usually one person, or an outside provider.
