IDOT’s Project Development Process
IDOT has a three-phase project development process:
- Phase I (or the project study) consists of developing the project scope, environmental studies, public involvement, and preliminary design of the project.
- Phase II (design) consists of refining the design to develop contract plans and conduct land acquisition.
- Phase III (construction) consists of the actual construction of the project.
