INDOT owns or is responsible for maintaining a roadway network totaling nearly 11,000 centerline miles and over 28,000 total lane miles throughout the state, including interstate highways, non-interstate National Highway System (NHS), roads and non-NHS roads.
Using historical analysis on pavement replacement costs, INDOT estimates $1 million is required to rebuild one lane-mile of highway. Assuming this cost, INDOT would have a total need of over $28 billion to rebuild its entire highway system. Therefore, INDOT’s pavement strategies help ensure the right treatments are performed at the right time in the most cost-effective manner.
INDOT’s Office of Pavement Design is responsible for the pavement design analyses that guide INDOT’s strategies for new, reconstruction, rehabilitation, and preservation projects for INDOT’s roadways.
