Marine Transportation Data
The Marine Transportation Data webpage provides centralized access to data resources, mapping applications, and analytical tools that support planning, investment, and decision-making for Illinois’ marine transportation system. Information provided includes infrastructure, freight movement, navigation, environmental, economic, and project-related data developed by IDOT and data collected from trusted federal, state, and regional partners.
These resources are intended to support port districts, local agencies, federal and state partners, planning organizations, industry stakeholders, and the public by improving access to marine transportation information used for infrastructure planning, project development, freight analysis, economic development, and system performance evaluation.
