Each dot is one bid, placed by the year its letting opened. Every price is restated to 2026 dollars and a typical job, so a price bid years ago and one bid last season compare like for like. Ink ticks: each year’s weighted median, where the year has at least 3 bids.

Where these numbers come from
Basis
Anchor proof test. 57 public bids on 11 lettings and 11 pay lines, from CTDOT and MassDOT (2019–2026). Every bid is restated to 2026 dollars and to a typical ESC job of 6 EA. A letting’s weight halves every 3 years, and each letting counts once, however many bidders it drew.
ESC’s rate is compared as a general contractor carries it: the published typical rate plus 10%, because a public pay line is the general contractor’s price, markup included.
