INDOT says interstate construction costs jumped in FY2026; agency cites inflation, major projects
Indiana Capital Chronicle reports INDOT presented a late‑August State Budget Committee slide showing a higher FY2026 average cost per centerline mile for interstate construction. INDOT attributed the rise to inflation, higher material and supply‑chain costs and cited programs including Revive I‑70 and Safer Drive 65.
According to Indiana Capital Chronicle reporting (Oct. 2, 2026), INDOT shared a late‑August State Budget Committee slide that presented its FY2026 average cost per centerline mile and listed projects included in the calculation, including the Revive I‑70 and Safer Drive 65 programs. The slide and agency comments framed the figures as statewide contract averages.
INDOT told the outlet that inflation in material costs, pandemic supply‑chain issues and the complexity of urban work and maintenance‑of‑traffic setups on corridors such as I‑70 and I‑65 are key drivers. The report also notes INDOT’s use of 20‑year asset‑management plans and alternative delivery methods; a source quoted concerns that data centers and other demand are competing with road builders for materials.
