Steps
Go to the FLH Escalation Factors pages under Construction Contracting (highways.dot.gov/federal-lands/business/escalation-factors) — separate EFL (Eastern), CFL (Central), and WFL (Western) sections exist
Download the year-specific 'Average Monthly Asphalt Prices' PDF (e.g. efl-asphalt-2026.pdf) and 'Average Monthly Fuel Prices' PDF for the relevant division and year
Read the 'How does Fuel/Asphalt Escalation Work' PDF to understand the SCR-based escalation formula
Apply the published monthly price against the contract's baseline (bid-month) price per the escalation clause
Known gotchas
Data is published as separate per-year static PDFs, not a queryable API or JSON feed — there is no unified historical endpoint
EFL, CFL, and WFL (the three FLH divisions) publish separate price tables; using the wrong division's index for a project will misstate the adjustment
