2024 Intersection Safety Project

McHenry County issued RFQ 23‑6752 for the 2024 Intersection Safety Project, a Phase I preliminary‑engineering effort to improve safety at three county intersections in unincorporated areas. The scope includes site surveys, drainage and wetland studies, crash‑analysis, traffic‑data compilation, design studies, environmental permitting, public outreach, and coordination with utilities and the Illinois Department of Transportation. HDR Engineering, Inc. was awarded the contract; Phase II design services are optional pending Phase I outcomes. The work is funded by federal‑aid dollars, with an estimated construction cost of $3 million per intersection (total ~$9 million) and engineering fees to be negotiated after qualification evaluation. • Engineering services: surveys, hydrology, geotechnical, traffic & crash analysis, design studies, environmental coordination. • Deliverables: multiple technical reports, design packages, public‑involvement documentation, and, if awarded, full design plans & cost estimates for Phase II. • Schedule: RFQ posted 2 Nov 2023; submissions due 22 Nov 2023; staff review 27 Nov‑4 Dec 2023; interviews 18 Dec 2023; County Board approval anticipated 19 Mar 2024; project start anticipated 25 Mar 2024.
