Project Overview

Washington County selected us to provide preliminary and final design on CSAH 22 from US 61 to Hinton Avenue in Cottage Grove, Minnesota. A highlight of the project was converting this 2-lane rural roadway to primarily an urban section with the addition of a shared-use trail along the majority of the corridor.


Beyond Design

In addition, we are also under contract to update and prepare a corridor study from US 61 to TH 95 (Manning Avenue).

Our traffic engineering services on this project and study included traffic operations and safety analysis at 22 key intersections, intersection control evaluations, intersection traffic control design, traffic impact studies, traffic forecasting, signal justification reports, capacity analysis, and a feasibility study with cost estimates.


Community Responsibility

Our public outreach services on this project included project newsletters, multiple open houses, elected official workshops, stakeholder meetings, and branding, including the project logo. We also created a project website and managed project-related social media content. These strategies were developed to keep the community informed as well as provide more channels for project input.
