Stephenson County Highway Department, Illinois, is soliciting proposals for Phase I and Phase II engineering services, with an option for Phase III, for a roundabout at County Highway 6 (Galena Road) and County Highway 5 (Cedarville Road), with proposals due 3:00 PM on November 9, 2026. The source's jurisdiction field lists St. Clair County (FIPS 17163), which conflicts with the issuing county.

Scope covers data collection, environmental studies coordination, local coordination, IDOT forms and reports, pavement design options, safety improvements, intersection evaluation, a Project Development Report, contract plans and specifications, cost and time estimates, right-of-way acquisition, and land appraisal and negotiation services. The estimated construction cost is $3.5 million, funded entirely through Federal Rural and Tribal Assistance grant funds. Phase I and Phase II engineering is expected to be complete for a spring 2028 state letting.

Proposals are limited to 10 pages and must include a cover letter, an organizational chart with key staff, resumes limited to two pages total, a supporting staff listing, proposed sub-consultants, relevant completed projects of similar scope and magnitude, and a project approach section.
