Indiana reports $46M average per centerline mile for interstate construction in FY2026 as costs surge
Indiana spent an average of $46 million per centerline mile of interstate in the 2026 state fiscal year (ended June 2026), up nearly 450% from $8.4 million in fiscal 2015, a slide shown at a late‑August State Budget Committee meeting said. Officials cite inflation, higher steel and concrete prices, supply shortages and a shift to larger-capacity projects; the Federal Highway Administration’s index rose more than 60% from 2020–2025.
A state slide presented in late August shows Indiana spent an average $46 million to construct a centerline mile of interstate in the 2026 fiscal year (ended June 2026), versus $8.4 million in fiscal 2015. Indiana Department of Transportation and industry leaders told reporters the rise reflects inflation, higher material costs (notably steel and concrete), supply‑chain shortages, and a move from resurfacing to larger, urban capacity projects; INDOT cited the Revive I‑70 and Safer Drive 65 efforts as examples of complex, costly work.
