The Illinois 100/106, Florence Bridge, River Crossing Study was started in April 2016, and was initially anticipated to take three years to complete. This study represents the Phase I, planning portion of the project, which provides preliminary engineering and environmental impact evaluation to guide the project in future phases of work. Phase I studies are now scheduled for completion in fall 2021. The replacement of the Florence Bridge is included in IDOT's FY 2023-2028 Highway Improvement Program which includes funding for preliminary & construction engineering, archeology surveys, land acquisition, utility relocations and construction.
