IDOT’S THREE-PHASE PROJECT DEVELOPMENT PROCESS
Proposed highway improvements are typically processed in three phases. In Phase I (preliminary engineering phase), proposed geometry, environmental concerns, and right-of-way requirements are defined. This phase generally takes an estimated 24 months to complete. During Phase II, contract plans are prepared, and the necessary right-of-way is acquired. This phase generally takes an estimated 12-24 months to complete. Phase III represents the actual construction of the improvement. This phase generally takes an estimated 18-24 months to complete. This project is currently in Phase II.
