I-57 at IL-17 Interchange Reconstruction
Study
Overview and Scope
Proposed improvements involve roadway reconstruction on I-57 and IL 17 (Court Street) with drainage, intersection and safety improvements as needed. Alignment changes are proposed along I-57 and will require replacement of the bridges carrying Waldron Road and the KB&S Railroad over I- 57. Permanent and temporary closure or relocation of some local streets and entrances will be necessary. Acquisition of additional right of way will be required. An analysis of potential highway traffic noise impacts was performed during the study in accordance with Department policy.
The study is anticipated to be completed in calendar year 2020. Phase II (Design) engineering is currently funded in the Fiscal Year (FY) 2021-2026 Proposed Highway Improvement Program and would begin after approval of the Phase I project study, subject to funding availability.
Land Acquisition and Construction are unfunded in the FY 2021-2026 Proposed Highway Improvement Program.
Land Acquisition, Utility Adjustments, and Construction funding for replacement of the bridge carrying Waldron Road over I-57 are included in the FY 2021-2026 Proposed Highway Improvement Program.
More information on Land Acquisition processes is available under the resources section below.
