The IL Route 47 study area is located in McHenry County extending approximately 8 miles from north of Reed Road to south of US 14. Existing IL Route 47 carries as much as 20,800 ADT with 5% trucks on a two lane roadway. The volume is anticipated to increase up to 26,000 vehicles per day by the year 2040. The corridor is developed with a mix of residential, commercial and industrial land uses at the northern and southern limits and primarily agricultural land in the central section. The study area traverses through five communities including Huntley, Lake of the Hills, Lakewood, Crystal Lake and Woodstock. The study area is experiencing growth with much of the land in the central section slated for residential or commercial development.
The project was designated as a Context Sensitive Solutions (CSS) project. CSS is a collaborative approach that involves all stakeholders to develop a facility that fits into its surroundings and preserves scenic, aesthetic, historic and environmental resources while maintaining safety and mobility. As part of the CSS process, numerous public meetings and stakeholder workshops have been held throughout the course of the project.
This project is being processed as an Environmental Assessment (EA). The EA Report describes the purpose and need of the proposed project, alternatives considered, the recommended preferred alternative, anticipated environmental impacts, project benefits, and potential mitigation measures.

Note: IDOT projects typically have three distinct phases. Phase I (or the project Study) consists of developing the project scope, environmental studies and preliminary design of a project. Phase II (Design) consists of refining the design to develop contract plans and land acquisition. Phase III (Construction) consists of the actual construction of the project.
