Indiana Capital Chronicle: INDOT reports higher interstate construction costs in FY2026 tied to materials, labor and project complexity

The Indiana Capital Chronicle (Oct. 2, 2026) reported that INDOT's average cost to construct a centerline mile of interstate increased in the 2026 state fiscal year. The article attributes the rise to inflation, big increases in steel and concrete, labor and materials costs, competition with data centers for equipment and supplies, and inclusion of more major capital projects rather than routine resurfacing.

The article notes what INDOT counts in the reported per‑centerline‑mile costs — lane replacements, widened shoulders, barrier walls, traffic and drainage work, materials and labor — and says two particularly complicated interstate projects were part of the fiscal‑year average. INDOT officials described using project bundling and alternative delivery methods and pointed to 20‑year asset‑management planning as part of how the agency schedules work.
