Indiana interstate construction averaged $46M per centerline mile in FY2026, up nearly 450% since 2015
Indiana Capital Chronicle reported Oct. 2, 2026 that the Indiana Department of Transportation’s FY2026 average construction cost was $46 million per centerline mile (state fiscal year ended June 2026), up nearly 450% from $8.4 million in FY2015. The story cites inflation, materials and complex projects such as Revive I-70 and Safer Drive 65.
Indiana Capital Chronicle (by Leslie Bonilla Muñiz, Oct. 2, 2026) reported that INDOT’s average cost to construct a centerline mile of interstate in the 2026 state fiscal year (ended June 2026) was $46 million. The FY2026 average included complex projects such as Revive I-70 (Wayne County) and Safer Drive 65 (Scott and Clark counties) and covers full reconstruction and added travel lane work.
The article says the increase — nearly 450% from the $8.4 million average in FY2015 — reflects factors the department and industry cited: higher material and labor costs, supply-chain shortages, pandemic aftereffects, tariffs, competition for concrete and steel from data centers, and the extra traffic-management and engineering needed for urban and high-volume interstate projects.
