A typical roadway project in Illinois is developed and implemented using a three-phase process:
Contract Plan Preparation and Land Acquisition
Phase I: Preliminary Engineering and Environmental Studies
During this phase, the project team will collect information, identify transportation issues, assess environmental concerns, facilitate public involvement, develop engineering solutions, analyze alternatives, and identify potential effects to study area resources. The project team will study a broad range of alternatives to improve the Interchange as well as a “no build” alternative.
Phase II: Contract Plan Preparation and Land Acquisition
Phase II includes Contract Plan Preparation and Land Acquisition for the interchange improvements. Phase II typically takes approximately two years. Typically, Phase II does not start until all funding has been secured for the improvement.
Phase III: Construction
Phase III is construction of the improvement and would take approximately two years.
