Annual Highway Improvement Program

Each year, IDOT develops the Annual Highway Improvement Program, also referred to as the Proposed Improvements for Illinois Highways. This publication presents a more detailed account of the applicable fiscal year’s highway program element, originally presented in the related Multi-Modal Multi-Year Transportation Improvement Program. It is designed to provide an overview of the program, as well as a current listing of all projects in an effort to inform the general public and aid local transportation stakeholders and business partners in specific planning activities.


MYP projects and specifically highway projects from the Annual Highway Improvement Program can be viewed on an interactive map using IDOT’s Getting Around Illinois website. Please click here to visit the interactive map, and to view the current program’s projects.


The FY 2018 program comes with a unique set of challenges. While the budget passed by the Illinois General Assembly in July 2017 appropriated $2.2 billion for capital improvements to Illinois' highway system in FY 2018, the General Assembly passed legislation to transfer $303 million in funds traditionally obligated from the General Revenue Fund to the Road Fund. After these reduction's, the available revenues for the FY 2018 highway program stand at $1.9 billion.

The revised FY 2018 program includes a total of 408 miles of highways and 156 bridges to be improved or constructed. Safety and traffic improvements are scheduled at 40 locations. The FY 2018 program includes $1.367 billion for projects on the state highway system and $747 million for projects on the local system.
