I-80 Ridge Road to US Route 30 Study

The I-80 Ridge Road to US Route 30 study area begins at Ridge Road to the west and ends at U.S. Route 30 to the east, a distance of approximately 16 miles. The corridor encompasses three counties (Kendall, Grundy and Will), and passes through 6 municipalities (Minooka, Channahon, Shorewood, Rockdale, Joliet and New Lenox), and consists of a diverse mixture of land uses including agricultural, residential, commercial and industrial with rural, suburban and urban characteristics. The roadway crosses 4 waterways including the Des Plaines River, includes 8 interchanges, and handles heavy truck traffic.

The I-80 Phase I Preliminary Engineering and Environmental Study will take a detailed look at the current and future transportation needs of the corridor. The study will include an analysis of existing roadway and bridge deficiencies, safety and capacity issues, and future transportation needs, and includes an extensive public involvement process. IDOT will continue to reach out and engage stakeholders throughout the Phase I study process through a variety of opportunities and methods intended to maximize public participation in the identification of project solutions.


Note: IDOT projects typically have three distinct phases. Phase I (or the project Study) consists of developing the project scope, environmental studies and preliminary design of a project. Phase II (Design) consists of refining the design to develop contract plans and land acquisition. Phase III (Construction) consists of the actual construction of the project.
