Field Analysis and Intersection Improvements Study

Yellowstone County is seeking an engineering firm to conduct a comprehensive field‑analysis and intersection‑improvement study for up to eight intersections within the county. The consultant will collect traffic data, perform crash‑history and sight‑distance analyses, model future conditions, and develop prioritized short‑, mid‑ and long‑term improvement recommendations complete with planning‑level cost estimates. The effort culminates in a draft report due June 1 2026 and final deliverables by June 30 2026. • Perform traffic data collection, operational performance analysis, and on‑site surveys of selected intersections. • Conduct crash‑history review, sight‑distance evaluation, and future‑traffic modeling. • Produce prioritized improvement recommendations (short, mid, long term) with feasibility commentary, cost estimates, and right‑of‑way considerations. • Deliver a draft study for county review (June 1) and a final report (June 30).
